Camera: fix status tracker race condition

Request thread may race with disconnect call when device is
disconnected in error condition. Acquire mLock when camera
device is updating status tracker to prevent that race
(status tracker being freed and then updated).
In other places where status tracker is updated, there is
a promoted sp to guarantee status tracker remain alive during
the call.

Test: CTS, manual camera testing
