HID: kye: fix unresponsive keyboard
The manticore keyboard requires that all usb EP are opened at least once to be fully functional. The third EP forwards to the user space some vendor specific information about the keyboard state, but are useless currently for the kernel. Opening them and closing them makes the keyboard responsive again.
