fpsensor: Deinit the sensor before clearing the context
The opaque context contains sensor state that we can't nuke from
underneath the sensor library. Calling fp_sensor_deinit will release
this context and allow us to safely clear the context.
BRANCH=none
BUG=b:124773209
TEST="fpenroll" followed by "fpclear" in the FP console
TEST=On nocturne, in the UI, enroll finger, log out, and log in
=> then lock and unlock with finger
TEST=make buildall -j
