Mark Johnston 59f3eb3b71 netinet: Explicitly disallow connections to the unspecified address 
If the V_connect_ifaddr_wild sysctl says that we shouldn't infer a
destination address, return an error.  Otherwise it's possible for use
of an unspecified foreign address to trigger a subsequent assertion
failure, for example in in_pcblookup_hash_locked().

Similarly, if no interface addresses are assigned, fail quickly upon an
attempt to connect to the unspecified address.
