[PATCH rcu 5/8] torture: Permit kvm-again.sh --duration to default to previous run

[Boqun Feng]

From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>

Currently, invoking kvm-again.sh without a --duration argument results
in a bash error message.  This commit therefore adds quotes around the
$dur argument to kvm-transform.sh to allow a default duration to be
taken from the earlier run.
