anv/image: Remove extra dependency on HiZ-specific variable

surf_usage is only useful to image views that may use HiZ buffers.
Storage image views don't use HiZ buffers.

v2: Update commit message and add an assertion.

Fixes: 055ff2ec521 ("anv: Replace anv_image_has_hiz() with ISL_AUX_USAGE_HIZ")
