media: i2c: max9286: fix access to unallocated memory
The asd allocated with v4l2_async_notifier_add_fwnode_subdev() must be
of size max9286_asd, otherwise access to max9286_asd->source will go to
unallocated memory.
Fixes: 86d37bf31af6 ("media: i2c: max9286: Allocate v4l2_async_subdev dynamically")
