Module name:	LVM2

Modified files:
	lib/metadata   : metadata.c 

Log message:
	Remove useless memory allocation for pv->vg_name in _alloc_pv().
	
	All this seems to do is provide a memory leak so remove it.
	The only caller of _alloc_pv() later explicitly sets
	pv->vg_name = fmt->orphan_vg_name so clearly this allocation
	should be removed.  I also saw no where in the code where
	strncpy was used to assign pv->vg_name - only direct assignments
	and strdup's.
