[PATCH] IB: Fix timeout/cancelled MAD handling
Fixes an issue processing a sent MAD after it has timed out or been canceled.
The race occurs when a response MAD matches with the send request. The
request could time out or be canceled after the response MAD matches with the
request, but before the request completion can be processed.
