Do not dereference the 'dmn' until after the virStateCleanup is completed.

During initialization, virStateInitialize requires/uses the "dmn" as the
argument to/for the daemonInhibitCallback functions. Thus, cleanup cannot
dereference 'dmn' until after calling the virStateCleanup which calls the
the daemonInhibitCallback using 'dmn'; otherwise, the following crash occurs:
