It would be nice if we could make the SRQ and non-SRQ code paths more
similar and shrink the code.  But I'm not sure there's any reason to
post a send work request in the non-SRQ case -- we can just destroy the
QP after the last pending receive completes (but we have to wait for
them all to complete before destroying the QP).
