ansible: don't check if nbdkit plugin works properly (RHBZ#1847898)

The check is currently failing on latest EL8. After discussion it turned
out that calling the nbdkit properly so that it universaly works is not
so trivial anymore. It seems best to remove the deployment check and let
virt-v2v do it properly before conversion.
