[KJ] [PATCH] remove unused return in drivers/block/pktcdvd.c

Found this on Coverty's linux bug database (http://linuxbugsdb.coverity.com) if anyone else is interested, you can ask
for a login at linuxbugs@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. 

This patch applies to linus' latest Git tree 099d44e869f1886b5eb02a5145ca97b5e4142e28.
