IB/umad: make sure write()s have sufficient data
Make sure that userspace passes in enough data when sending a MAD. We
always copy at least sizeof (struct ib_user_mad) + IB_MGMT_RMPP_HDR
bytes from userspace, so anything less is definitely invalid. Also,
if the length is less than this limit, it's possible for the second
copy_from_user() to get a negative length and trigger a BUG().
