libs: encoder: h264: initialize all elements of view_ids

Currently when num_views is changed by multiview-mode on sink caps, it produces
wrong MVC encoded stream since the array view_ids is not set properly according
to changed num_views.

So this patch initializes all of the array sequentially to handle this case.
Side effect is not going to happen by this patch since this array is being
handled by num_views.
