msm: camera: sensor: Power down in case of cci init failure

Currently power down is not happening in case of cci_init failure.
This can lead to corruption for the next power up, as power down
did not happen for the previous session. This change does power down
in case of cci failure and as a part of that it can power up resources
correctly in next session.
