Subject: drm/i915: Improve i915_inject_probe_error macro
Git-commit: b58a8813ee6d65e98ee02b3d3036c6a75ac7e694
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

On non-debug builds we were not using i915 param and thus
we may cause "unused variable" warning/error if caller was
not using i915 elsewhere. Let compiler see this param.
