RDMA/mad: Reject receive completions shorter than GRH
ib_mad_recv_done() derives the OPA MAD length by subtracting the GRH
size from wc->byte_len without ensuring the receive completion covers
the GRH. If it is shorter, the subtraction wraps before the result is
stored in mad_len and an invalid length can be passed downstream.
Reject receive completions shorter than the GRH before inspecting the
MAD header or deriving the MAD length.
