For Alcor Corp. Slave camera(1b17:6684), it support to
output compressed video data, and it return a wrong
dwMaxPayloadTransferSize fields. This is a fireware issue,
but the manufacturer cannot provide a const return fields
by the fireware. so we check the dwMaxPayloadTransferSize fields,
if it large than 0x1000, reset dwMaxPayloadTransferSize to 1024.
