Richard Kennedy 58a9d3d8db fs-writeback: check sync bit earlier in inode_wait_for_writeback 
When wb_writeback() hasn't written anything it will re-acquire the inode
lock before calling inode_wait_for_writeback.

This change tests the sync bit first so that is doesn't need to drop &
re-acquire the lock if the inode became available while wb_writeback() was
waiting to get the lock.
