[PATCH] drivers/block/pktcdvd.c: remove write-only variable in pkt_iosched_process_qu...

Found this on Coverty's linux bug database (http://linuxbugsdb.coverity.com).

The function pkt_iosched_process_queue makes a call to bdev_get_queue and
stores the result but never uses it, so it looks like it can be safely
removed.
