virsh: Use old API if remote libvirtd does not support new

Commit ffe28ab74b821c916ec4ba8efb5c992454e4bd24 introduced regression
while communicating with older libvirtd command 'domblkstat' used the new
API and did not check for VIR_ERR_RPC error code signalling the remote
server does not support this API and did not fall back to older API.
Thereafter 'domblkstat' ended with "error: unknown procedure: 243".
