Roland Dreier 39798695b4 IB/mad: Fix race between cancel and receive completion 
When ib_cancel_mad() is called, it puts the canceled send on a list
and schedules a "flushed" callback from process context.  However,
this leaves a window where a receive completion could be processed
before the send is fully flushed.

This is fine, except that ib_find_send_mad() will find the MAD and
return it to the receive processing, which results in the sender
getting both a successful receive and a "flushed" send completion for
the same request.  Understandably, this confuses the sender, which is
expecting only one of these two callbacks, and leads to grief such as
a use-after-free in IPoIB.

Fix this by changing ib_find_send_mad() to return a send struct only
if the status is still successful (and not "flushed").  The search of
the send_list already had this check, so this patch just adds the same
check to the search of the wait_list.
