[libvirt] [PATCH v2 3/6] libxl: Resolve Coverity FORWARD_NULL

Since the strtok_r call in libxlCapsInitGuests expects a non NULL first parameter when the third parameter is NULL, we need to check that the returned 'capabilities' from a libxl_get_version_info call is not NULL and error out if so since the code expects it.
