Subject: [PATCH v3] HID: Apply quirk HID_QUIRK_ALWAYS_POLL to Edifier QR30 (2d99:a101)

The USB speaker has a bug that causes it to reboot when changing the
brightness using the physical knob.

Add a new vendor and product ID entry in hid-ids.h, and register
the corresponding device in hid-quirks.c with the required quirk.

Signed-off-by: Rodrigo Lugathe da Conceição Alves <lugathe2@...il.com>
