block: remove bogus check for queue_lock assignment

Browse source 
We just allocated the queue and haven't even set it up yet,
hence we know that checking if ->mq_ops is NULL is always
going to be true.

In fact we do need to assign a lock to ->queue_lock always,
as we need it for the queue flags modifications.
