d3bdcd5963 RDMA/irdma: Report correct WC error when transport retry counter is exceeded
When the retry counter exceeds, as the remote QP didn't send any Ack or
Nack an asynchronous event (AE) for too many retries is generated. Add
code to handle the AE and set the correct IB WC error code
IB_WC_RETRY_EXC_ERR.

5b1e985f76 RDMA/irdma: Skip CQP ring during a reset
Due to duplicate reset flags, CQP commands are processed during reset.

This leads CQP failures such as below:

 irdma0: [Delete Local MAC Entry Cmd Error][op_code=49] status=-27 waiting=1 completion_err=0 maj=0x0 min=0x0

Remove the redundant flag and set the correct reset flag so CPQ is paused
during reset

41f5fa9fa7 RDMA/irdma: Change the returned type of irdma_set_hw_rsrc to void
Since the function irdma_set_hw_rsrc always returns zero, change the
returned type to void and remove all the related source code.

2db7b2eac7 RDMA/irdma: Store PBL info address a pointer type
The level1 PBL info address is stored as u64.  This requires casting
through a uinptr_t before used as a pointer type.

And this leads to sparse warning such as this when uinptr_t is missing:

drivers/infiniband/hw/irdma/hw.c: In function 'irdma_destroy_virt_aeq':
drivers/infiniband/hw/irdma/hw.c:579:23: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
  579 |  dma_addr_t *pg_arr = (dma_addr_t *)aeq->palloc.level1.addr;

This can be fixed using an intermediate uintptr_t, but rather it is better
to fix the structure irdm_pble_info to store the address as u64* and the
VA it is assigned in irdma_chunk as a void*. This greatly reduces the
casting on this address.
