drm/amd/display: Use memset to initialize variables in amdgpu_dm_atomic_commit_tail

Clang warns:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5089:60:
warning: suggest braces around initialization of subobject
[-Wmissing-braces]
                struct dc_surface_update dummy_updates[MAX_SURFACES] = { 0 };
                                                                         ^
                                                                         {}

Previous efforts to fix this type of warning by adding or removing
braces have been met with some pushback in favor of using memset [1][2].
Do that here, mirroring commit 05794eff1aa6 ("drm/amdgpu/gmc: fix
compiler errors [-Werror,-Wmissing-braces] (V2)") in this tree.
