rtl8187b: do not do per packet TX AGC
Clearing the per packet TX AGC for the RTL8187B device appears to increase its overall TX power. This allows the device to associate and a connection to be established using APs a little further away. This is in accordance to what is done for RTL8187L devices and also what Realtek drivers do.
