bdevperf: free job configs at the end of test run 



It makes it to possible to use different bdevs on subsequent
"perform_tests" runs, as the bdev will now be selected just before
running the tests and not at the start of the application.

This can be useful, when the first set of tests are supposed to be run
on one bdev, but then switch to another one without having to restart
the application.  E.g.:

$ build/examples/bdevperf -z -t 8 -w randread -q 128 -o 4096 &
$ scripts/rpc.py bdev_null_create null0 100 4096
$ examples/bdev/bdevperf/bdevperf.py perform_tests
