RDMA/irdma: Fix data race on CQP completion stats
CQP completion statistics is read lockesly in irdma_wait_event and irdma_check_cqp_progress while it can be updated in the completion thread irdma_sc_ccq_get_cqe_info on another CPU as KCSAN reports.
Make completion statistics an atomic variable to reflect coherent updates to it. This will also avoid load/store tearing logic bug potentially possible by compiler optimizations.

RDMA/irdma: Refactor HW statistics
Refactor HW statistics which,
- Unifies HW statistics support for all HW generations.
- Unifies support of 32- and 64-bit counters.
- Removes duplicated code and simplifies implementation.
- Fixes roll-over handling.
- Removes unneeded last_hw_stats.
With new implementation, there is no separate handling and no separate arrays for 32- and 64-bit counters (offsets, regs, values). Instead, there is a HW stats map array for each HW revision, which defines HW-specific width and location of each counter in the statistics buffer.
Once the statistics are gathered (either via CQP op, or by reading HW registers), counter values are extracted from the statistics buffer using the stats map and the delta between the last and new values is computed. Finally, the counter values in rdma_hw_stats are incremented by those deltas.
From the OS perspective, all the counters are 64-bit and their order in rdma_hw_stats->value[] array, as well as in irdma_hw_stat_names[], is the same for all HW gens. New statistics should always be added at the end.
