Subject: drm/i915/guc: Refactoring preparation of the GUC_CTL_CTXINFO parameter

Git-commit: 741cebee0aa59cdaafb798c66171c2a863c3fa32
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
At the moment, the preparation of GUC_CTL_CTXINFO is disordered.
Lets move all GUC_CTL_CTXINFO related operations to one place.
v2:
- move 'ctxnum' and 'base' declarations to USES_GUC_SUBMISSION case
