Zdenek Kabelac 91419c3e86 Fix use of released vgname and vgid 
Avoid using of already released memory when duplicated MDA is found.

As get_pv_from_vg_by_id() may call lvmcache_label_scan() use the local copy
of the vgname and vgid on the stack as vginfo may dissapear and code was
then accessing garbage in memory.

i.e.  pvs  /dev/loop0
(when /dev/loop0 and /dev/loop1 has same MDA content)
