Pad HID output reports on Windows to the maximum output report size.

Pad HID output reports on Windows to the maximum output report size.

The Windows HID library requires output report buffers to be exactly
the maximum length specified in the OutputReportByteLength field of
HIDP_CAPS. This patch automatically pads output reports to this length
with zeros and rejects reports longer than this length.
