[ Upstream commit b97cca3ba9098522e5a1c3388764ead42640c1a5 ]

In commit 02b9984d6408, we pushed a sync_filesystem() call from the VFS
into xfs_fs_remount.  The only time that we ever need to push dirty file
data or metadata to disk for a remount is if we're remounting the
filesystem read only, so this really could be moved to xfs_remount_ro.

Once we've moved the call site, actually check the return value from
sync_filesystem.

Fixes: 02b9984d6408 ("fs: push sync_filesystem() down to the file system's remount_fs()")
