But after the commit removing virDomainSetMemory usage it changed to:
no option | --current | --live | --config | --live --config

LIVE | CURRENT | LIVE | LIVE & CONFIG | LIVE & CONFIG
This commit fixes the logic back to the original behavior except for

Currently `virt-host-validate` will fail whenever one of its calls fail,
regardless of virHostValidateLevel set.
This behaviour is not optimal and makes it not exactly reliable as a
command line tool as other tools or scripts using it would have to check
its output to figure out whether something really failed or if a warning
was mistakenly treated as failure.
With this change, the behaviour of whether to fail or not, is defined by
the caller of those functions, based on the virHostValidateLevel passed
to them.
