ml80211: Put wiphy idx to obtain correct country code

Browse source 
If wiphy idx not provided, kernel returns global reg domain when
processing NL80211_CMD_GET_REG. To obtain the correct country code for
the self-managed regulatory cases, put wiphy idx into nl_msg when
sending this command to kernel.
