In the file sync path, file's parent inode is logged if it is newer than the last
commit. This patch checks also the last_trans field as well as generation.
As btrfs_log_inode updates the logged_trans field of parent dir's inode, tree-log
lookup operations are suppressed upon unlink.
The patch is for the latest btrfs-unstable tree.
