v4l2-ioctl: change to long return type to match unlocked_ioctl.

From: Hans Verkuil <hverkuil@xs4all.nl>

Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.

Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.

Priority: normal
