Pretty trivial, below. This also keeps the queue mapping calculations
more clean, as we don't have to do one after we're done allocating
IRQs.

Yep, this addresses my concern. It less efficient than PCI since PCI
can usually jump straight to a valid vector count in a single iteration
where this only subtracts by 1. I really can't be bothered to care for
optimizing that, so this works for me! :) 

It definitely is less efficient than just getting the count that we
can support, but it's at probe time so I could not really be bothered
either.

Can I add your reviewed-by?

Yes, please.
