Nick Desaulniers e637aa32b8 biometrics: fingerprint: add locking to default impl ...

There exists the following race condition:
a). thread A receives setNotify and sets the callback to some object
b). thread B of the wrapped implementation calls
BiometricsFingerprint::notify which it was given a handle to. Thread B
executes past the nullptr check:
c). thread A receives setNotify and sets the callback to some other
object (or nullptr)
d). thread B resumes in notify with unknown state

Add mutex to protect access to mClientCallback.
