Log message:
	Fix vgextend error path - if ORPHAN lock fails, unlock and release vg.
	
	Full changes
	- Fix vgextend error path when lock_vol(VG_ORPHANS) fails
	- Move lock_vol(VG_ORPHANS) before archive(vg) - safe & simpler error paths
	- Remove legacy comment/code that no longer applies
	
	Found in review - Milan Broz <mbroz@redhat.com>
