qed: Align CIDs according to DORQ requirement
The Doorbell HW block can be configured at a granularity of 16 x CIDs, so we need to make sure that the actual number of CIDs configured would be a multiplication of 16. Today, when RoCE is enabled - given that the number is unaligned, doorbelling the higher CIDs would fail to reach the firmware and would eventually timeout.
