net: spider_net: do not read mac address again after setting it
This patch removes the spider_net_get_mac_address() call at the end of
the spider_net_set_mac() function. The dev->dev_addr is instead updated
with a memcpy() from sa->sa_data.
Since spider_net_get_mac_address() is not used anywhere else, this patch
also removes the function.
