Subject: [PATCH] net: wireless: rtlwifi: rtl8192de: hw.c:  Cleaning up conjunction always evaluates to false

Expression '(X & 0xfc) == 0x3' is always false

I chose to remove this code, because it will not make any difference.
But obviously it is rather a properly designed if statement that is needed.

This was partly found using a static code analysis program called cppcheck.
