Subject: [PATCH] HID: quirks: avoid Cooler Master MM712 dongle wakeup bug

The Cooler Master Mice Dongle includes a vendor defined HID interface
alongside its mouse interface. Not polling it will cause the mouse to
stop responding to polls on any interface once woken up again after
going into power saving mode.

Add the HID_QUIRK_ALWAYS_POLL quirk alongside the Cooler Master VID and
the Dongle's PID.
