HID: quirks: Add ALWAYS_POLL quirk for Beitong BTP-KP20D dongle

Browse Source 
The BTP-KP20D dongle in Direct/HID mode (20dd:5159) re-enumerates every
few seconds because usbhid never submits its interrupt-IN URB: no HID
driver binds to the vendor-specific report descriptor, so the device is
never opened, and the firmware treats the idle endpoint as a lost link.

Add HID_QUIRK_ALWAYS_POLL to keep the interrupt-IN URB submitted from
probe time.
