[PATCH 09/11] media: cedrus: initialize controls a bit later

While it doesn't matter if controls are initialized before or after
queues and formats from open handler standpoint, initializing them last
helps keeping s_ctrl handler simpler, since everything has already valid
values.

This is just preparation for follow up changes. No functional change is
intended.
