Subject: [PATCH 2/2] ubifs: Reduce kfree() calls in ubifs_purge_xattrs()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 26 Sep 2024 11:28:48 +0200

Move a pair of kfree() calls behind the label “out_err”
so that two statements can be better reused at the end of
this function implementation.
