Set from even if binfo->extra is NULL.
bgpd/bgp_packet.c:bgp_update_packet(): When extracting the peer, don't fail to extract it because "binfo->extra" is NULL. While one should certainly avoid dereferencing binfo->extra, that's not a good reason not to use binfo->peer. Fixes https://bugzilla.quagga.net/show_bug.cgi?id=497. Patch by Eric Sobocinksi.
