During connection setup, the application may choose to zero-size inbound

handling of zero-sized queues, but not prevents it.
Kamal Heib says in an initial error report:
When running the blktests over siw the following shift-out-of-bounds is
reported, this is happening because the passed IRD or ORD from the ulp
could be zero which will lead to unexpected behavior when calling
roundup_pow_of_two(), fix that by blocking zero values of ORD or IRD.
