fs: sort out the fallocate mode vs flag mess
The fallocate system call takes a mode argument, but that argument
contains a wild mix of exclusive modes and an optional flags.
Replace FALLOC_FL_SUPPORTED_MASK with FALLOC_FL_MODE_MASK, which excludes
the optional flag bit, so that we can use switch statement on the value
to easily enumerate the cases while getting the check for duplicate modes
for free.
To make this (and in the future the file system implementations) more
readable also add a symbolic name for the 0 mode used to allocate blocks.
