s390/scm_blk: fix endless loop for requests != REQ_TYPE_FS

The while loop only peeks at the top request in the queue but does
not yet consume it. Since we only handle fs requests, we need to
dequeue and complete all other request command types with error
just in case we would ever receive such an unforeseen request.
