Bitterblue Smith 3240476a5b wifi: rtw88: 8822c: Fix reported RX band width
commit a71ed5898dfae68262f79277915d1dfe34586bc6 upstream.

"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.
