block: pass a queue_limits argument to blk_alloc_disk
Pass a queue_limits to blk_alloc_disk and apply it if non-NULL. This
will allow allocating queues with valid queue limits instead of setting
the values one at a time later.
Also change blk_alloc_disk to return an ERR_PTR instead of just NULL
which can't distinguish errors.
