zram: remove request_queue from struct zram

Browse source

`struct zram' contains both `struct gendisk' and `struct request_queue'.
the latter can be deleted, because zram->disk carries ->queue pointer, and
->queue carries zram pointer:

create_device()
	zram->queue->queuedata = zram
	zram->disk->queue = zram->queue
	zram->disk->private_data = zram

so zram->queue is not needed, we can access all necessary data anyway.
