libceph: fix msgr backoff
With commit f363e45f we replaced a bunch of hacky workqueue mutual exclusion logic with the WQ_NON_REENTRANT flag. One pieces of fallout is that the exponential backoff breaks in certain cases: * con_work attempts to connect. * we get an immediate failure, and the socket state change handler queues immediate work. * con_work calls con_fault, we decide to back off, but can't queue delayed work. In this case, we add a BACKOFF bit to make con_work reschedule delayed work next time it runs (which should be immediately). Signed-off-by: Sage Weil <sage@newdream.net>
