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

Convert QP object to follow IB/core general allocation scheme. That
change allows us to make sure that restrack properly kref the memory.

Coverity reports a signed 32-bit overflow on "1 << pprm->pble_shift" when
used expression to compute bits_needed that expects 64bit, unsigned.
Fix this by using the 1ULL in the left shift operator and convert mem_size
to u64.

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.
