Are we going to use the queue_wait field of struct request_queue
someday? As of 2.6.0-test2, I don't see any use of it. If it's not
needed anymore, the following patch gets rid of it. Tested this patch by
compiling for i386 and also doing a grep through all .h and .c files to
see if it's used somewhere else (admittedly weak).
