Input: elantech - reset the device when elantech probe fails

elantech_init() calls elantech_set_absolute_mode which sets the driver in
an absolute mode. When after this the elantech_init fails, it is best to
turn the ps/2 mouse emulation mode back on by calling psmouse_reset() so
that it can work as a regular mouse.
