From: Roman Li <[email protected]>
[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.
Fixes: cdaae8371aa9 ("drm/amd/display: Handle GPU reset for DC block")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3808
