Don't test possibly uninitialized variable in wxGCDC::SetLogicalFunction().

Browse Source 
The variable "mode" is not filled by TranslateRasterOp() function if the input
function is not supported, so don't compare it with wxCOMPOSITION_XOR later.
Just compare "function" itself with wxXOR as this works in any case.
