Michal Privoznik 4e00d7fb04 nodeDeviceParseMdevctlJSON: Accept empty string
It is possible for 'mdevctl' to output nothing, an empty string
(e.g. when no mediated devices are defined on the host). What is
weird is that when passing '--defined' then 'mdevctl' outputs an
empty JSON array instead. Nevertheless, we should accept both and
treat them the same, i.e. as no mediated devices.
