If btrfs_log_dentry_safe() returns an error, we set ret to 1 and
fall through with the goal of committing the transaction. However,
in the case where the inode doesn't need a full sync, we would call
btrfs_wait_ordered_range() against the target range for our inode,
and if it returned an error, we would return without commiting or
ending the transaction, leaving the transaction open forever.
Since when btrfs_wait_ordered_range() doesn't return an error we
commit the transaction, it doesn't make sense to make a call to
btrfs_wait_ordered_range() because committing the transaction will
wait for all ordered extents to complete anyway.
