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
