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.
