[PATCH] drm/amd/display: Drop stream_for_cursor from dcn10_apply_ctx_for_surface

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

The main motivation was that it was at least theoretically possible for
stream_for_cursor to be dereferenced when it was NULL.

The code also becomes slightly smaller, and hopefully easier to
understand.
