Log message:
	Remove reset of vg->vgmem pointer as it is access of already release memory
	
	This reset of vgmem pointer causes access of already released memory.
	(_vg_make_handle allocates vg from vgmem pool itself - which is a bit tricky)
	
	Interestingly this memory fault was missed by our test suite.
