Subject: [PATCH] wifi: mwl8k: initialize cmd->addr[] properly

This loop is supposed to copy the mac address to cmd->addr but the
i++ increment is missing so it copies everything to cmd->addr[0] and
only the last address is recorded.

Fixes: 22bedad3ce11 ("net: convert multicast list to list_head")
