lib: unset ZEBRA_IFA_PEER if no dst addr present (BZ#801)
On OpenBSD, carp interfaces claim to be PtP interfaces with a 0.0.0.0/0
peer address. We process those in zebra and try to send them to
clients, at which point they get encoded as all-0. The client code,
however, decodes that to a NULL pointer instead of 0.0.0.0. This later
turns into a SEGV when CONNECTED_PREFIX sees that ZEBRA_IFA_PEER is set
and tries to access the peer prefix.
This is a band-aid fix for stable/0.99.23, a long-term solution needs
some conceptual improvements on the entire thing.
(The usefulness of a PtP-to-0.0.0.0/0 is a separate question; at this
point dropping the peer prefix seems the least intrusive solution.)
