synaptics: Immediately complete verification if finger removed

Browse source 
When quickly scanning a finger with the synaptic driver, it may wait forever
for finger removal even if this has already happened.

In fact we don't take care of the finger status when reporting the
verification.

To avoid this, add a function that delays the completion of the verification
until the finger removal if the finger is on sensor, otherwise it just
performs it.

Fixes #228
