android: generic_camera_buffer: Fix bufferLength_ initialization

The bufferLength_ member variabled is checked to have a positive value
before being used, to catch usage before the variable is set. The
variable is initialized to zero at construction time, which renders the
checks useless.

Fix this by initializing the variable to -1 at construction time.
