VTVDA: Handle more missing IDR situations.

VTVDA: Handle more missing IDR situations.

This CL reduces the conditions on dropping frames to just
|waiting_for_idr_|. We don't need to consider whether there is a pending
config change (this should be a decode error if we are not waiting) or
whether |session_| is set (|waiting_for_idr_| covers this).
