commit 834124c596e2dddbbdba06620835710ccca32fd0 upstream.

The Venus v1 behaves differently comparing with the other Venus
version in respect to capability parsing and when they are send
to the driver. So we don't need to initialize hfi parser for
multiple invocations like what we do for > v1 Venus versions.

Fixes: 10865c98986b ("media: venus: parser: Prepare parser for multiple invocations")
