[PATCH 4/5] btrfs: Use common error handling code in update_ref_path()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Mon, 21 Aug 2017 13:34:29 +0200

Add a jump target so that a bit of exception handling can be better reused
in this function.

This issue was detected by using the Coccinelle software.
