[PATCH 09/20] drm/amd/display: Assign stream status for FPO + Vactive cases

From: Alvin Lee <alvin.lee2 at amd.com>

A new check was added to ensure FPO is not enabled when the FPO pipe has
0 planes. This requires the stream status to check the plane count, but
the stream status was not assigned for FPO + Vactive cases which leads
to FPO not be enabled always.
