[Intel-gfx] [PATCH 04/11] drm/i915: remove useless memset() for watermarks parameters

[Paulo Zanoni]

The skl_compute_plane_wm_params() already completely sets the contents
of its struct, or returns plane_visible=0 or returns an error code.
There's no need to memset() it at this point for the same reason we
don't zero-initialize it up when dealing with plane 0.

If we want to keep the memset "just to be safe", then we should also
zero initialize it when we use it for plane 0.
