accel/habanalabs/gaudi2: use correct registers to dump QM CQ info
The QM CQ PTR_LO/PTR_HI/TSIZE registers are for pushing a CQ entry, and
although they are updated by HW even when descriptors are fetched by PQ
and CB addresses are fed into CQ, the correct registers to use when
dumping the CQ info are the ones with the _STS suffix.
