[ Upstream commit dcb23bbb1de7e009875fdfac2b8a9808a9319cc6 ]
When a QP and a MR on a local host are in different PDs, the HW generates an asynchronous event (AE). The same AE is generated when a QP and a MW are in different PDs during a bind operation. Return the more appropriate IBV_WC_MW_BIND_ERR for the latter case by checking the OP type from the CQE in error.
