mt76: mt7921: fix firmware usage of RA info using legacy rates

Browse source

According to the firmware usage, OFDM rates should fill out bit 6 - 13
while CCK rates should fill out bit 0 - 3 in legacy field of RA info to
make the rate adaption runs propertly. Otherwise, a unicast frame might be
picking up the unsupported rate to send out.
