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.

+UFS Options
+===========
+
+ufstype=type_of_ufs
+	UFS is a file system widely used in different operating systems.
+	The problem are differences among implementations. Features of
+	some implementations are undocumented, so its hard to recognize
+	type of ufs automatically. That's why user must specify type of
+	ufs manually by mount option ufstype. Possible values are:
+
+	old
+                old format of ufs
+		default value, supported as read-only
+
+	44bsd
+                used in FreeBSD, NetBSD, OpenBSD
+		supported as read-write
+
+	ufs2
+                used in FreeBSD 5.x
+		supported as read-write
+
+	5xbsd
+                synonym for ufs2
+
+	sun
+                used in SunOS (Solaris)
+		supported as read-write
+
+	sunx86
+                used in SunOS for Intel (Solarisx86)
+		supported as read-write
+
+	hp
+                used in HP-UX
+		supported as read-only
+
+	nextstep
+		used in NextStep
+		supported as read-only
+
+	nextstep-cd
+		used for NextStep CDROMs (block_size == 2048)
+		supported as read-only
+
+	openstep
+		used in OpenStep
+		supported as read-only
