[Cluster-devel] [PATCH 2/5] libgfs2: clean up some dead code in gfs2_writei

[Andrew Price <anprice@redhat.com>]

This patch cleans up an error variable which was initialized to 0 and
then never changed, and a 'fail' section which could be replaced by a
return. It also removes the 'out' label which was only referenced from
the dead if-statement in the 'fail' section.
