If remote server has been resolved to multiple addresses, at
least one connection attemt has been made and connection to
the last address was skipped by management - resolved earlier
link socket addrinfo objects will not be cleared neither on
instance close nor in the next connection entry loop.
This causes fatal error assert:
>REMOTE:openvpn.net,1194,udp
remote ACCEPT
SUCCESS: remote command succeeded
>REMOTE:openvpn.net,1194,udp
remote SKIP
SUCCESS: remote command succeeded
>FATAL:Assertion failed at init.c:504
(c->c1.link_socket_addr.current_remote == NULL)
Fix this behaviour by cleaning stale addinfo objects.
