Today uc_fini_hw is subset of uc_sanitize, but remaining
code in sanitize function is also desired for uc_fini_hw.
Instead of duplicating the code, just call uc_sanitize,
but leave as separate function to maintain symmetry with
uc_init_hw.

We should drop call to uc_fini_hw from gem_fini as part of this patch as
GuC won't be available then.
But we will need it in gem_fini to properly finish our cleanup on unload.
Maybe to keep symmetry, we should add i915_gem_fini_hw and call it from
there ? See cleanup inside i915_gem_init_hw.
