drm/i915/uc: Do full sanitize instead of pure reset

Browse source

On Gen9 when we try to reload HuC due to GuC upload error, we hit:

<7> [229.656688] [drm:intel_uc_init_hw [i915]] GuC fw load failed: -8; will reset and retry 2 more time(s)
<7> [229.656739] [drm:intel_uc_fw_upload [i915]] HuC fw load i915/kbl_huc_ver02_00_1810.bin
<3> [229.656740] intel_uc_fw_upload:425 GEM_BUG_ON(intel_uc_fw_is_loaded(uc_fw))

as we performed only pure reset and didn't sanitized HuC fw status.
