media: v4l2-ioctl: Push NULL fh argument down to ioctl wrappers

As ioctl handlers do not expect a priv argument anymore, start pushing
the NULL pointer down from __video_do_ioctl() to the ioctl wrappers.
This paves the way to dropping the void *priv argument to ioctl handlers
themselves.

Changes to ioctl wrappers have been generated with the following
coccinelle semantic patch:

@ioctl@
identifier v4l2_ioctls;
identifier ioctl;
identifier fn;
identifier debug;
expression flags;
@@
struct v4l2_ioctl_info v4l2_ioctls[] = {
	...,
	IOCTL_INFO(ioctl, fn, debug, flags),
	...,
};

@depends on ioctl@
identifier ioctl.fn;
identifier ops;
identifier file;
identifier fh;
identifier arg;
identifier handler;
expression list args;
@@
-int fn(const struct v4l2_ioctl_ops *ops, struct file *file, void *fh, void *arg)
+int fn(const struct v4l2_ioctl_ops *ops, struct file *file, void *arg)
{
	<...
-	ops->handler(file, fh, args)
+	ops->handler(file, NULL, args)
	...>
}

Manual changes have been added to handle the calls to
v4l_[gs]_selection(), drop the fh argument in the v4l2_ioctl_info
structure definition and in the DEFINE_V4L_STUB_FUNC() macro, and stop
passing NULL to the wrappers in __video_do_ioctl()
