wifi: mt76: mt7921: fix the wrong rate pickup for the chanctx driver
[ Upstream commit 32b1000db221df33ec8b57794a091ba6075b6c28 ]
The variable band should be determined by the ieee80211_chanctx_conf when
the driver is a kind of chanctx one e.g mt7921 and mt7922 driver so we
added the extension to mt76_connac2_mac_tx_rate_val by distinguishing if
it can support chanctx to fix the incorrect rate pickup.
