protocol/client: conn-id should be unique when lk-heal is off
Problem:
It was observed that in some cases client disconnects
and re-connects before server xlator could detect that a
disconnect happened. So it still uses previous fdtable and ltable.
But it can so happen that in between disconnect and re-connect
an 'unlock' fop may fail because the fds are marked 'bad' in client
xlator upon disconnect. Due to this stale locks remain on the brick
which lead to hangs/self-heals not happening etc.
For the exact bug RCA please look at
https://bugzilla.redhat.com/show_bug.cgi?id=1049932#c0
Fix:
When lk-heal is not enabled make sure connection-id is different for
every setvolume. This will make sure that a previous connection's
resources are not re-used in server xlator.
