wifi: rtlwifi: rtl8192cu: Fix 2T2R chip type detection
rtl8192cu handles 1T1R devices (RTL8188CUS), 1T2R devices (RTL8191CU),
and 2T2R devices (RTL8192CU). The 2T2R devices were incorrectly detected
as 1T2R because of a mistake in the IS_92C_1T2R macro.
The visible effect of this is that the firmware was allowed to use
TX rates only up to MCS7.
Fix the IS_92C_1T2R macro.
Now my 2T2R device has much better upload speed.
Before: 46 Mbps.
After: 82 Mbps.
Also fix a debug message which was printing "RF_1T1R" even for 1T2R
chips.
