media: iris: Simplify session stop logic by relying on vb2 checks

commit 0fe10666d3b4d0757b7f4671892523855ee68cc8 upstream.

Remove earlier complex conditional checks in the non-streaming path that
attempted to verify if stop was called on a plane that was previously
started. These explicit checks are redundant, as vb2 already ensures
that stop is only called on ports that have been started, maintaining
correct buffer state management.
