This needs a FIXME at least.
For starters we need to drop requests until the ctx match (i.e. while
(rq->ctx != port_request(port)->ctx)) and then we have the issue that we
may have the same ctx multiple times in an N slot elsp. So
while (rq->ctx != port_rquest(port)->ctx || i915_gem_request_completed(port_request(port)))
?
