[Mesa-dev] [RFC v2 11/22] anv: Handle failure in make_hiz_surface_maybe()

[Louis-Francis Ratté-Boulianne]

From: Chad Versace <chadversary at chromium.org>

make_ccs_surface_maybe() correctly handles failure
isl_surf_get_ccs_surf(). When it fails, the resultant VkImage is still
valid, just without a ccs surface.

Same of make_mcs_surface_maybe() and isl_surf_get_mcs_surf().

Fix make_hiz_surface_maybe() to do the same.
