drm/amd/display: Fix stale buffer object (bo) use
Fixes stale buffer object (bo) usage for cursor plane Cursor plane's bo operations are handled in DC code. Currently, atomic_commit() does not handle bo operations for cursor plane, as a result the bo assigned for cursor plane in dm_plane_helper_prepare_fb() is not coherent with the updates to the same made in dc code.This mismatch leads to "bo" corruption and hence crashes during S3 entry. This patch cleans up the code which was added as a hack for 4.9 version only.
