slirp: Fix ICMP error sending
Disambiguation : icmp_error is renamed into icmp_send_error, since it doesn't manage errors, but only sends ICMP Error messages. Signed-off-by: Yann Bordenave <meow@meowstars.org> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Reviewed-by: Thomas Huth <thuth@redhat.com>
