The client connection loop was a bit of a mess. It only slept between
retries in one particular case. Other failures to connect would spin
and livelock. It would spin forever.
This fixed loop now has a much more orderly reconnect procedure. Each
connecting sender always tries once. Then retry attempts backoff
exponentially, settling at a nice long timeout. After long enough it'll
return errors.
This fixes livelocks in the xfstests that mount and unmount around
dm-flakey config. generic/{034,039,040} would easily livelock before
this fix.
