efl net - handle proxy helper fails better and abort proxy lookups

if proxy fails are too many then give up on queued lookups as they
likely will continue. i noticed a process continually spawning efl net
proxy helper because one queued lookup failed and could be looked up
so it kept trying again and again.

@fix
