Double completion?  When the QP exits RTS with pending unsignaled SQ WRs, cxgb4
doesn't know if those were actually completed by hardware, so they are completed
with FLUSH_ERR status.  I _could_ change cxgb4 to just eat those, but I'm a
little worried about breaking the iWARP Verbs semantics.  Perhaps I shouldn't
be.  It does seem to be causing lots of pain...
