xfs: remove ->write_super and stop maintaining ->s_dirt
the write_super method is used for
(1) writing back the superblock periodically from pdflush
(2) called just before ->sync_fs for data integerity syncs
We don't need (1) because we have our own peridoc writeout through xfssyncd,
and we don't need (2) because xfs_fs_sync_fs performs a proper synchronous
superblock writeout after all other data and metadata has been written out.
Also remove ->s_dirt tracking as it's only used to decide when too call
->write_super.
