RDMA/irdma: Fix legacy i40iw compat check in create_qp

The irdma driver maintains backward compatibility with the
legacy i40iw userspace provider by checking the length of
the user response buffer in irdma_create_qp.

Previously, the check relied on udata->outlen < sizeof(uresp).
That is technically okay since there have only ever been two
sizes for the resp struct (legacy and current). However, it
would be a problem if the resp struct is ever expanded in
the future because it would end up triggering the legacy
fallback path for non-legacy irdma providers that just  haven't
moved over to the newer expanded struct yet.

Fix this by explicitly checking for the exact legacy resp size.
