Move local variable declaration to the beginning of the function

Browse Source 
Older versions of MSVC (for example when using Visual Studio 10) don't
yet support variable declaration in the middle of blocks:

hidapi\windows\hid.c(845) : error C2275: 'BOOL' : illegal use of this type as an expression
        C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\windef.h(153) : see declaration of 'BOOL'

Move the declaration of res to the beginning of the function.  Like in
hid_get_feature_report, only res is moved, essentially ignoring the #if
0 block (or assuming it will never be enabled).
