[PATCH 3.14 09/43] btrfs: simplify insert_orphan_item

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: David Sterba <dsterba@suse.cz>

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.
