test/qos: allow more variance due to iSCSI overhead 



Running iSCSI in loopback runs into some cases where
a core is considerably impacted by the initiator
TCP traffic, even though the scheduler is trying
to schedule it on different cores.  Gang is working
through modifying the QoS tests to just use bdevperf
instead of iSCSI, but until that is ready, let's
allow more variance to reduce the fairly significant
rate of test failures we're seeing due to this test.
