[ Upstream commit 5575b7646b94c0afb0f4c0d86e00e13cf3397a62 ]
The driver maintains a CQ table that is used to ensure that a CQ is still valid when processing CQ related AEs. When a CQ is destroyed, the table entry is cleared, using irdma_cq.cq_num as the index. This field was never being set, so it was just always clearing out entry 0.
Additionally, the cq_num field size was increased to accommodate HW supporting more than 64K CQs.
