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

Browse source

[ Upstream commit 5511ba3de4 ]

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.
