Fix unlikely password change leakHEADmaster

In kpasswd_sendto_msg_callback(), if getsockname() does not reveal the
local address, a copy of the first local address's contents is made
and never freed.  Instead of making an allocated copy of the address
contents, make a shallow copy of the whole address.  Delay freeing the
address array until the end of the function so that alias pointer made
by the shallow copy remains valid.
