wifi: rtw89: set data lowest rate according to AP supported rate

Browse Source 
By default the driver uses the 1M and 6M rate (0x0) for data frames in
2 GHz and 5/6 GHz bands respectively. But the rate that might not AP
supported. Therefore, We modify the data lowest rate according to the
lowest of AP supported rate.
