xfs: improve log incompat feature handling
This patchset improves the performance of log incompat feature bit
handling by making a few changes to how the filesystem handles them.
First, we now only clear the bits during a clean unmount to reduce calls
to the (expensive) upgrade function to once per bit per mount. Second,
we now only allow incompat feature upgrades for sysadmins or if the
sysadmin explicitly allows it via mount option. Currently the only log
incompat user is logged xattrs, which requires CONFIG_XFS_DEBUG=y, so
there should be no user visible impact to this change.
