wifi: rtl8xxxu: Fix HT40 channel config for RTL8192CU, RTL8723AU

Browse source

Flip the response rate subchannel. It was backwards, causing low
speeds when using 40 MHz channel width. "iw dev ... station dump"
showed a low RX rate, 11M or less.

Also fix the channel width field of RF6052_REG_MODE_AG.

Tested only with RTL8192CU, but these settings are identical for
RTL8723AU.
