drm/amd/display: Fix HWSS v3 fast path determination

[WHY]
We're checking surface and stream updates after they've been applied to
their respective states within `update_planes_and_stream_state`.

Medium updates under the HWSS V3 fast path that are not supported or
tested are getting implicitly if they don't trigger a DML validation
and getting updated in place on the dc->current_state context.

[HOW]
Fix this issue by moving up the fast path determination check prior
to `update_planes_and_stream_state`. This is how the V2 path works
and how the V3 path used to work prior to the refactors in this area.
