Re: [libvirt] [PATCH RESEND] libvirt: lxc: fix incorrect parameter of lxcContainerMountProcFuse

when we has no host's src mapped to container. there is no .oldroot dir,so libvirt lxc will fail to start when mouting meminfo. in this case,the parameter srcprefix of function lxcContainerMountProcFuse should be NULL.and make this method handle NULL correctly.
