media: i2c: Correct format propagation for st-mipid02 

[ Upstream commit 306c3190b3 ]

Format propagation in the st-mipid02 driver is incorrect in that when
setting format for V4L2_SUBDEV_FORMAT_TRY on the source pad, the
_active_ rather than _try_ format from the sink pad is propagated.
This causes problems with format negotiation - update the function to
propagate the correct format.
