commit 6f4669708a69fd21f0299c2d5c4780a6ce358ab5 upstream.
If we need to reset a symlink target to the "durr it's busted" string,
then we clear the zapped flag as well. However, this should be using
the provided helper so that we don't set the zapped state on an
otherwise ok symlink.

The atomic file exchange-range functionality is now a permanent
filesystem feature instead of a dynamic log-incompat feature. It cannot
be turned on at runtime, so we no longer need the XCHK_FSGATES flags and
whatnot that supported it. Remove the flag and the enable function, and
move the xfs_has_exchange_range checks to the start of the repair
functions.

If a symbolic link target looks bad, try to sift through the rubble to
find as much of the target buffer that we can, and stage a new target
(short or remote format as needed) in a temporary file and use the
atomic extent swapping mechanism to commit the results. In the worst
case, we replace the target with an overly long filename that cannot
possibly resolve.
