vxge: fix return of a free'd memblock on a failed dma mapping
Currently if a pci dma mapping failure is detected a free'd
memblock address is returned rather than a NULL (that indicates
an error). Fix this by ensuring NULL is returned on this error case.
Addresses-Coverity: ("Use after free")
Fixes: 528f727279ae ("vxge: code cleanup and reorganization")
