[PATCH weston v2] libinput: Suppress unhandled-case warning

When the wheel tilt source is present, gcc complains that we don't
handle all possible enumeration values. We already ensure this cannot
happen in its only caller (handle_pointer_axis), but gcc doesn't
recognise this. Give it a default value to quiet the warning.
