There is no cfg scheduler and new added kyber scheduler in lastest kernel,
so get the scheduler from sysfs
To reproduce it:
$ ./check nvmeof-mp/012
nvmeof-mp/012 (dm-mpath on top of multiple I/O schedulers) [passed]
runtime 5.922s ... 8.804s
$ cat results/nodev/nvmeof-mp/012.full | grep -n "Changing scheduler"
31:Changing scheduler of dm-3 from mq-deadline kyber [bfq] none into cfq failed
47:Changing scheduler of dm-3 from mq-deadline kyber [bfq] none into cfq failed
