wifi: rtw88: 8822c: Fix reported RX band width
"iw dev wlp2s0 station dump" shows incorrect rx bitrate:
tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
rx bitrate: 86.7 MBit/s VHT-MCS 9 VHT-NSS 1
This is because the RX band width is calculated incorrectly. Fix the
calculation according to the phydm_rxsc_2_bw() function from the
official drivers.
After:
tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
rx bitrate: 390.0 MBit/s VHT-MCS 9 80MHz VHT-NSS 1
It also works correctly with the AP configured for 20 MHz and 40 MHz.
Tested with RTL8822CE.
