It appears that sometimes the loop device doesn&amp;#39;t get setup properly,
this may be a race with other users of loop devices on the system, or
some other mechanism that isn&amp;#39;t understood.

To try and prevent total failure when this happens this patch retries
the loop setup 3 times before giving up. Previously it would wait for
the loop device to appear (checking 5 times), that operation is now
executed 3 times with a new losetup attempt each time.
