netcf: Don't complain when cleanup is called before init

Browse Source 
netcfStateInitialize() initializes the driverState variable,
and when netcfStateCleanup is called, it will call virReportError()
if driverState is NULL.
This is not consistent with what other state objects are doing,
they return -1 without reporting an error in such cases.
