Windows: Fixed an incorrect return type on HidP_GetCaps()

Browse Source 
Addresses an issue with the return type of HidP_GetCaps() which was
returning the wrong status code because of the invalid return type of
BOOLEAN which is a UCHAR. The return code is supposed to be 0x110000
which obviously doesn't fit in a UCHAR so it was being rounded to
0x0. Basically, no return codes were ever making it through that call.
