Description of problem:
when glusterd is restarted on the node from which volume is mounted on the
client, IO fails on the mountpoint. 'Transport endpoint is not connected' error
is seen.

How reproducible:
always

Steps to Reproduce:
1. on a 3 node gluster cluster, set cluster.brick-multiplex on
2. create a 2x3 volume
3. mount the volume and run IO
4. restart glusterd on the node from which volume is mounted
5. check if IO continues from the client

Actual results:
Transport endpoint not connected error is seen and IO halts

Expected results:
IO should continue and glusterd restart should not affect client IOs

Additional info:
No logs shall be attached as this is easily reproducible, let me know if
sosreports are needed
