[libvirt] [PATCH 1/7] lxc: Only check @nparams in lxcDomainBlockStatsFlags

[John Ferlan]

Remove the "!params" check from the condition since it's possible
someone could pass a non NULL value there, but a 0 for the nparams
and thus continue on.  The external API only checks if @nparams is
non-zero, then check for NULL @params.
