bail out of client_read if we've already decide what to do

libevent2 can still somehowe call client_read even in code paths
that never enable reading from the evbuffer.  Can't reproduce on
the libevent in base on OpenBSD.  It's a bit ugly, but it's a small
workaround for something that otherwise *always* make gmid crash
when linked against libevent2.  (client_read works under the
assumption that c->host != NULL, matched_proxy crashes otherwise.)
