These pointers can't be NULL so I have removed the checks.
The checking was sort of problematic as well because it didn't make
sense. In _nbu2ss_read_request_data() the && should have been ||. In
nbu2ss_gad_get_frame() we know that "pgadget" is non-NULL and "udc" is
an offset from "pgadget" so it can't be NULL.
