mxm_wifiex: fix the net_device::dev_addr build warnings on L5.16

Use eth_hw_addr_set function instead of writing the address directly to
net_device::dev_addr. Make sure we don't cast off const qualifier from
dev->dev_addr. Otherwise will have the build warnings when build the
driver based on L5.16 kernel.

Fixes: adeef3e32146 ("net: constify netdev->dev_addr")
