glusterd:upon re-peer probe glusterd should not return response to CLI two times
If a node N1 and node N2 is part of the cluster and a node N2 try to reprobe
node N1 when N1 is disconnected by any means (for eg: either server is down
or glusterd is not running or there is a network outage, or firewall is
blocking port number 24007 on which glusterd listen, etc.), then glusterd
trying to send back two responses to CLI resulting into a double free and
a glusterd crash.
With this fix glusterd will send response to cli only once and prevent
glusterd crash.
Note: glusterd was crashing only when user has done first peer probe with
hostname and re-probe with ip-address or vice-versa.
