lwip,pfinet: Fix crash on make_sock_user getting EINTR
_ports_create_port_internal may return EINTR.
* lwip/port-objs.c (make_sock_user): Set errno when ports_create_port
returns an error.
* pfinet/socket.c (make_sock_user): Likewise.
* lwip/io-ops.c (lwip_S_io_reauthenticate): Loop while make_sock_user
errors with EINTR.
* pfinet/io-ops.c (S_io_reauthenticate): Likewise.
