[media] media: au0828 set ctrl_input in au0828_s_input()
dev->ctrl_input is set in vidioc_s_input() and doesn't get set in
au0828_s_input(). As a result, dev->ctrl_input is left uninitialized
until user space calls s_input.
It works correctly because the default input value is 0 and which is
what dev->ctrl_input gets initialized via kzalloc().
Change to set dev->ctrl_input in au0828_s_input(). Also optimize
vidioc_s_input() to return if the new input value is same as the
current.
