Log message:
	Add free_orphan_vg
	
	Move commod code to destroy orphan VG into free_orphan_vg() function.
	Use orphan vgmem for creation of PV lists.
	Remove some free_pv_fid() calls (FIXME: check all of them)
	FIXME: Check whether we could merge release_vg back again for all VGs.

 Version 2.02.92 - 
 ====================================
+  Add free_orphan_vg.
   Skip pv/vg_set_fid processing if the fid is same.
   Check for foreach loop errors in _vg_read_orphans() (2.02.91).
   Clean error paths for format instance creation (2.02.91).
