Since the moment writes to quota files are using block device page cache and space for quota structures is reserved at the moment they are first accessed we have no reason to sync quota before inode writeback. In fact this order is now only harmful since quota information can easily change during inode writeback (either because conversion of delayed-allocated extents or simply because of allocation of new blocks for simple filesystems not using page_mkwrite). So move syncing of quota information after writeback of inodes into ->sync_fs method. This way we do not have to use ->quota_sync callback which is primarily intended for use by quotactl syscall anyway and we get rid of calling ->sync_fs() twice unnecessarily. We skip quota syncing for OCFS2 since it does proper quota journalling in all cases (unlike ext3, ext4, and reiserfs which also support legacy non-journalled quotas) and thus there are no dirty quota structures.
