[PATCH 15/24] sm-notify: Save mon_name and my_name strings

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

Currently sm-notify does not use the mon_name and my_name strings
passed to smn_get_host().  Very soon we're going to need the mon_name
and my_name strings, so add code to store those strings in struct
nsm_host, and free them when each host is forgotten.
