 ticket: 6949

 Remember and close the kadmin socket we opened.

 Prior to ticket #6746, the RPC library opened the kadmin socket and
 took responsibility for closing.  When we added IPv6 support, the
 calling code became the owner of the socket but wasn't closing it,
 resulting in a file descriptor leak.
