RDMA/irdma: Set irdma_cq cq_num field during CQ create

Browse Source 
[ 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.
