[PATCH] block: don't check request size in blk_cloned_rq_check_limits()

[Hannes Reinecke <hare@suse.de>]

When checking a cloned request there is no need to check
the overall request size; this won't have changed even
when resubmitting to another queue.
Without this patch ppc64le on ibmvfc fails to boot.
