drm/amd/display: Fix gpu reset in multidisplay config

commit 7eb287beeb60be1e4437be2b4e4e9f0da89aab97 upstream.

[Why]
The indexing of stream_status in dm_gpureset_commit_state() is incorrect.
That leads to asserts in multi-display configuration after gpu reset.

[How]
Adjust the indexing logic to align stream_status with surface_updates.
