ide-tape,floppy: fix failed command completion after request sense
Impact: fix infinite retry loop
After a command failed, ide-tape and floppy inserts REQUEST_SENSE in
front of the failed command and according to the result, sets
pc->retries, flags and errors. After REQUEST_SENSE is complete, the
failed command is again at the front of the queue and if the verdict
was to terminate the request, the issue functions tries to complete it
directly by calling drive->pc_callback() and returning ide_stopped.
However, drive->pc_callback() doesn't complete a request. It only
prepares for completion of the request. As a result, this creates an
infinite loop where the failed request is retried perpetually.
Fix it by actually ending the request by calling ide_complete_rq().
