libs: decoder: h264: initialize active_sps/pps in reset

Browse source 
Since commits in https://bugzilla.gnome.org/show_bug.cgi?id=781142 landed,
they introduced regression in seek.

Formerly, once seek is done, decoder drops P-frames until I-frame arrives.
But since the commits landed, it doesn't drop P-frame and does try to
decode it continuously because active_sps is still alive. See ensure_sps function.
But there are prev_frames and prev_ref_frames reset already, then it
causes assertion.

So it's necessary to reset active_sps/pps also in reset method.
