[PATCH 3.16.y-ckt 082/144] btrfs: simplify insert_orphan_item

[Luis Henriques]

3.16.7-ckt10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Sterba <dsterba@xxxxxxx>

commit 9c4f61f01d269815bb7c37be3ede59c5587747c6 upstream.

We can search and add the orphan item in one go,
btrfs_insert_orphan_item will find out if the item already exists.
