quota: clean up Q_XQUOTASYNC
Currently Q_XQUOTASYNC calls into the quota_sync method, but XFS does something entirely different in it than the rest of the filesystems. xfs_quota which calls Q_XQUOTASYNC expects an asynchronous data writeout to flush delayed allocations, while the "VFS" quota support wants to flush changes to the quota file. So make Q_XQUOTASYNC call into the writeback code directly and make the quota_sync method optional as XFS doesn't need in the sense expected by the rest of the quota code. GFS2 was using limited XFS-style quota and has a quota_sync method fitting neither the style used by vfs_quota_sync nor xfs_fs_quota_sync. I left it in for now as per discussion with Steve it expects to be called from the sync path this way. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
