i40iw: Use correct src address in memcpy to rdma stats counters

hw_stats is a pointer to i40_iw_dev_stats struct in i40iw_get_hw_stats().
Use hw_stats and not &hw_stats in the memcpy to copy the i40iw device stats
data into rdma_hw_stats counters.

Fixes: b40f475 ("IB/core: Make device counter infrastructure dynamic")
