media: vsp1: Remove unbalanced .s_stream(0) calls
The VSP1 driver uses the subdev .s_stream() operation to stop WPF
instances, without a corresponding call to start them. The V4L2 subdev
core started warning about unbalanced .s_stream() calls in commit
009905ec5043 ("media: v4l2-subdev: Document and enforce .s_stream()
requirements"), causing a regression with this driver.
Fix the problem by replacing the .s_stream() operation with an explicit
function call for WPF instances. This allows sharing an additional data
structure between RPF and WPF instances.
Fixes: 009905ec5043 ("media: v4l2-subdev: Document and enforce .s_stream() requirements")
