[PATCH 2/2] nvme-rdma: sqsize/hsqsize/hrqsize is 0-based val

Did we really decide that? The spec actually explicitly says
that a 0 sqsize will be failed:

"If the size is 0h or larger than the controller supports, then a
status value of Connect Invalid Parameters shall be returned."

And then it says: "This is a 0’s based value"

Confusing....
