Subject: [PATCH 4.5 086/101] btrfs: remove error message from search ioctl for nonexistent tree

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

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

From: David Sterba <dsterba@...e.com>

commit 11ea474f74709fc764fb7e80306e0776f94ce8b8 upstream.

Let's remove the error message that appears when the tree_id is not
present. This can happen with the quota tree and has been observed in
practice. The applications are supposed to handle -ENOENT and we don't
need to report that in the system log as it's not a fatal error.
