synaptics: Always report verify state early on non-match

Browse Source 
In some cases we want to complete the verification after that the finger has
been removed, but we still need to promptly report the match state otherwise
fpi-device will complain about, and will eventually cause a match error
instead that reporting a non-match:

  synaptics: Finger is now on the sensor
  synaptics: Received message with 0 sequence number 0x91, ignoring!
  synaptics: interrupt transfer done
  synaptics: delaying match failure until after finger removal!
  synaptics: interrupt transfer done
  device: Driver reported successful verify complete but did not report the
          result earlier. Reporting error instead
  libfprint: Failed to verify print: An unspecified error occured!

Fixes #227
