HID: input: fix uclogic tablets
commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT")
made the assumption that it was the only one handling tablets and thus
kept an internal state regarding the tool.
Turns out that the uclogic driver has a timer to release the in range
bit, effectively making hid-input ignoring all in range information
after the very first one.
Fix that by having a more rationale approach which consists in forwarding
every event and let the input stack filter out the duplicates.
