habanalabs/gaudi2: added memset for the cq_size register 



The clang-analyzer reported a warning: "Value stored to
'cq_size_addr' is never read".

The cq_size register of dcore0 is not being zeroed using
gaudi2_memset_device_lbw(), along with the other cq_* registers,
even though the corresponding cq_size_addr variable is set.
