Subject: [PATCH rcu 07/13] torture: Suppress "find" diagnostics from torture.sh --do-none run

From: "Paul E. McKenney" <paulmck@...nel.org>

When torture.sh is told to do nothing, it produces a couple of distracting
diagnostics from the "find" command:

	find: ‘’: No such file or directory
	find: ‘’: No such file or directory

This is pointless chatter and could cause confusion.  This commit therefore
suppresses these diagnostics when there is nothing to find.
