Add an API to allocate a request queue which accepts a custom set of
blk_mq_ops for that request queue.

The reason which we may want custom ops is for queuing requests which we
don't want to go through the normal queuing path.

Custom ops shouldn't be required for this. See e.g. how tmf_queue
is used in the UFS driver for an example of a queue implementation
with custom operations and that does not require changes of the block
layer core.

Thanks,

Bart.
