[ 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.
