Remove unnecesarry remount flag handling. This does not do anything for
this driver. We have already set SB_NODIRATIME when we fill super. Also
noatime should be set from mount option. Now for some reson we try to
set it when remounting.
Lazytime part looks like it is copied from f2fs and there is own mount
parameter for it. That is why they use it. We do not set lazytime
anywhere in our code. So basically this just blocks lazytime when
remounting.

Remove unnecesarry mount option noatime because this will be handled
by VFS. Our option parser will never get opt like this.

Usually in file system init() messages are only displayed in info level.
Change level from notice to info, but keep CONFIG_NTFS3_64BIT_CLUSTER in
notice level. Also this need even more attention so let's put big
warning here so that nobody will not try accidentally use it.
There is also no good reason to display internal stuff like binary tree
search. This is always on option which can only disabled for debugging
purposes by developer. Also this message does not even check if
developer has disabled it or not so it is useless info.

Capitalize comments and end with period for better reading.
Also function comments are now little more kernel-doc style. This way we
can easily convert them to kernel-doc style if we want. Note that these
are not yet complete with this style. Example function comments start
with /* and in kernel-doc style they start /**.
Use imperative mood in function descriptions.
Change words like ntfs -> NTFS, linux -> Linux.
Use "we" not "I" when commenting code.

Problem with these wrapper is that we cannot take off example GFP_NOFS
flag. It is not recomended use those in all places. Also if we change
one driver specific wrapper to kernel wrapper then it would look really
weird. People should be most familiar with kernel wrappers so let's just
use those ones.
Driver specific alloc wrapper also confuse some static analyzing tools,
good example is example kernels checkpatch tool. After we converter
these to kernel specific then warnings is showed.
Following Coccinelle script was used to automate changing.
virtual patch
@alloc depends on patch@
expression x;
expression y;

The static checkers (Smatch) were complaining because QuadAlign() was
buggy. If you try to align something higher than UINT_MAX it got
truncated to a u32.
Smatch warning was:
fs/ntfs3/attrib.c:383 attr_set_size_res()
warn: was expecting a 64 bit value instead of '~7'
So that this will not happen again we will change all these macros to
kernel made ones. This can also help some other static analyzing tools
to give us better warnings.
Patch was generated with Coccinelle script and after that some style
issue was hand fixed.
Coccinelle script:
virtual patch

We do not need our own implementation for this function in this
