xfs: shutdown xfs_sync_worker before the log
Revert commit 1307bbd, which uses the s_umount semaphore to provide exclusion between xfs_sync_worker and unmount, in favor of shutting down the sync worker before freeing the log in xfs_log_unmount. This is a cleaner way of resolving the race between xfs_sync_worker and unmount than using s_umount.
