osmo_sock_get_name_*: Ensure string is returned in error case

osmo_sock_get_name_buf():
In case the getsockname() call is failing for some weird reason,
we shouldn't return an uninitialized, non-zero-terminated string
buffer to the caller, as most callers will be too lazy to test the
return value.

This holds even more true for users of the internal
osmo_sock_get_name2() and osmo_sock_get_name2_c() functions which indeed
very much ignore the return value of osmo_sock_get_name_buf().
