Patch from Juha [êölä

When the block queue is plugged, mq->req must be set to NULL.
Otherwise mq->req might be left non-NULL, even though mmcqd is
not processing a request, thus preventing the MMC queue thread from
being woken up when new requests do arrive.

I'm not bothering with the full history, even though we have it.
