Please don't call tevent_req_simple_recv_ntstatus directly from a
_done routine, please create a wrapper for it. It might be idempotent,
but it is this kind of confusion around this routine that for example
caused the valgrind error you just fixed.

Maybe it's better to just remove this obviously very misleading
function and expand it into all its users. Do you want me to do this
to avoid this kind of discussion in the future? I can probably pretty
quickly get this patch done to remove this flawed abstraction.
