[Cluster-devel] [PATCH] libgfs2: Make sure secontext gets freed

Free sbd.secontext after is_pathname_mounted allocates it. As the RHEL6
metafs code has no construct/destruct model similar to upstream, the
secontext string has to be freed in a few places additional to
cleanup_metafs.
Resolves: #1121693
