selinux: ensure we cleanup the internal AVC counters on error in avc_update()
In AVC update we don't call avc_node_kill() when avc_xperms_populate()
fails, resulting in the avc->avc_cache.active_nodes counter having a
false value. In last patch this changes was missed , so correcting it.
Fixes: fa1aa143ac4a ("selinux: extended permissions for ioctls")
