[PATCH for-next v2 1/3] RDMA/rxe: Fix bug in get_srq_wqe() in rxe_resp.c

[Bob Pearson <rpearsonhpe@gmail.com>]

The memcpy() that copies a WQE from a SRQ the QP uses an incorrect size.
The size should have been the size of the rxe_send_wqe struct not the
size of a pointer to it. The result is that IO operations using a SRQ
on the responder side will fail.

Fixes: ec0fa2445c18 ("Fix over copying in get_srq_wqe")
