drm/i915/dp_mst: Clear the ACT sent flag during encoder disabling too
During encoder enabling we clear the flag before starting the ACT sequence and wait for the flag, but the clearing is missing during encoder disabling, add it there too. Since nothing cleared the flag automatically we could've run subsequent disabling steps too early.
