[PATCH v2] migration: free 'saddr' since be no longer used

[Zongmin Zhou]

Since socket_parse() will allocate memory for 'saddr',and its value
will pass to 'addr' that allocated by migrate_uri_parse(),
then 'saddr' will no longer used,need to free.
But due to 'saddr->u' is shallow copying the contents of the union,
the members of this union containing allocated strings,and will be used after 
that.
So just free 'saddr' itself without doing a deep free on the contents of the 
SocketAddress.
