vp9: Provide a default initializer for "hidden" member

The API of VP9 exposes a WasFrameHidden() function which accesses this
member. Given the constructor previously didn't initialize this member,
it's a potential vector for an uninitialized read.

Instead, we can initialize this to a deterministic value to prevent that
from occurring.
