synaptics: Fix problem after match is failed

Browse source 
This fixes the the problem that the sensor becomes unresponsive after
pressing the wrong fingerprint. We fix the problem by making sure that
the non-match report is delayed until the finger is removed. With this
we cannot run into the situation that the next match request fails
immediately as the finger is still present.

Fixes: #208
