media: v4l2-ctrls: Set error v4l2_ctrl_new_fwnode_properties consistently
The vast majority of the callers of v4l2_ctrl_new_fwnode_properties() do
check the returned error code but the function does not set the control
handler's error on failure. This will make error handling more complicated
and prone for bugs.
Always assign the control handler's error field on error in
v4l2_ctrl_new_fwnode_properties().
