[PATCH] mt76: fix determining multicast frame in sta mode

[sean.wang at mediatek.com]

From: Sean Wang <sean.wang at mediatek.com>

We should use hdr->addr3 as the destination address to determine the frame
is multicast frame or not when the device is running in sta mode.

We can simply use ieee80211_get_DA for ap mode and sta mode both cases.
