qlecontroller_win: fix GetLastError() bug in getServiceSystemPath()
Fix strange bug in getServiceSystemPath() where after the
first call to SetupDiGetDeviceInterfaceDetail(), GetLastError()
returns 0 instead of ERROR_INSUFFICIENT_BUFFER (122).
A fix is to use a `const DWORD` for the error immediately after
the SetupDiGetDeviceInterfaceDetail() call. Possibly a compiler
issue.
Target toolchain is:
gcc version 5.3.0 (i686-posix-dwarf-rev0, Built by MinGW-W64 project)
