scftorture: Count single_rpc offline failures in statistics outputgrafted

scf_torture_stats_print() aggregates each invoker thread's counters
into a local scf_statistics structure before printing, but the
n_single_rpc_ofl field is missing from the aggregation loop.  As a
result, the "single_rpc_ofl" value printed in the statistics line is
always zero, even when smp_call_function_single() invocations for the
RPC test have failed due to offline CPUs and been counted by the
invoker threads.

Add the missing accumulation so that the printed value reflects the
actual counts.

+====================
+Intel Display Driver
+====================
+
+The Intel display driver provides the display, or :ref:`drm-kms`, support for
+both the :ref:`drm/xe <drm/xe>` and :ref:`drm/i915 <drm/i915>` Intel GPU
+drivers.
+
+The source code currently resides under ``drivers/gpu/drm/i915/display`` due to
+historical reasons, and it's compiled separately into both drm/xe and drm/i915
+kernel modules.
+
+The drm/xe and drm/i915 drivers are the "core" or "parent" drivers for display,
+as they initialize and own the drm device, and pass that on to the display
+driver. The display driver isn't an independent driver in that sense.
