vos: print_addrs never receives multi-homed addrs

The magic address that tells the vlserver that a host is multi-homed,
and to look up the multi-homed address structure is an internal
implementation feature, which shouldn't be exposed to clients.

print_addrs is only ever called with the results of VL_GetAddrsU, which
has already converted any multi-homed pointers, so it doesn't need the
logic to handle them itself.
