HID: multitouch: fix Elan panels with 2 input modes declaration
When implementing commit 7f81c8db5489 ("HID: multitouch: simplify
the settings of the various features"), I wrongly removed a test
that made sure we never try to set the second InputMode feature
to something else than 0.
This broke badly some recent Elan panels that now forget to send the
click button in some area of the touchpad.

Title:
ASUS touchpad right button not working
Status in Ubuntu-Certification:
Invalid
Status in linux package in Ubuntu:
Fix Committed
Bug description:
On my ASUS T304UA, the right button of the trackpad generates no input event
whereas the left button and the left half part of the middle button works
(checked with libinput-debug-events).
I checked with the latest available kernel: 4.17.0-041700rc2-generic
Needless to say that the trackpad perfectly works under Windows.
The device is:
Bus 001 Device 005: ID 0b05:184a ASUSTek Computer, Inc.
I guess that the corresponding kernel driver is: hid_multitouch
Example of libinput-debug-events : left click then right click :
-event17 POINTER_BUTTON +1.11s BTN_LEFT (272) pressed, seat count: 1
event17 POINTER_BUTTON +1.23s BTN_LEFT (272) released, seat count: 0
It seems that there is a bug in the trackpad driver...
