accel/habanalabs/gaudi2: get the correct QM CQ info upon an error

Browse source

Upon a QM error, the address/size from both the CQ and the ARC_CQ are
printed, although the instruction that led to the error was received
from only one of them.

Moreover, in case of a QM undefined opcode, only one of these
address/size sets will be captured based on the value of ARC_CQ_PTR.
However, this value can be non-zero even if currently the CQ is used, in
case the CQ/ARC_CQ are alternately used.

Under the assumption of having a stop-on-error configuration, modify to
use CP_STS.CUR_CQ field to get the relevant CQ for the QM error.
