[PATCH 24/26] statd: Support IPv6 in sm_stat_1_svc()

[Chuck Lever <chuck.lever@oracle.com>]

SM_STAT is usually not used by most contemporary NSM implementations,
but for consistency, it gets the same treatment as sm_mon_1_svc(),
since both should use the same logic to determine whether a mon_name
is able to be monitored.
