Fix FAIL_PAUSE_OPREPO hanging enqueueAndWait callers

When an operation execution returns FAIL_PAUSE_OPREPO, the repo is
paused and the ops are re-queued with their original waiters still
attached. enqueueAndWait callers (loginSuspend) would suspend on
the waiter forever — the op stays in the queue but never executes
while paused, and the waiter is never woken.

Wake the waiter with false and re-queue with waiter=null, matching
the pattern from #2600.
