media: atomisp: Do not turn off sensor when the atomisp-sub-dev does not own it

The atomisp driver creates 8 /dev/video# device nodes. 4 nodes (preview /
video / viewfinder / capture) for each of 2 possible streams aka
atomisp-sub-device-s (asd-s).

Both streams start with asd->input_curr set to 0 (to the first sensor),
opening + releasing a file-handle on one of the nodes of an asd,
while streaming from the other asd causes the sensor to get turned off,
leading to the stream failing.

The atomisp-code already tracks which asd "owns" a specific sensor,
use this to only turn the sensor off if it is owned by the asd.
