In the policy handle hashing, handle more than one policy handle having
the same value, as an open might return handle XXX, handle XXX might
then be closed, and a subsequent handle might return handle XXX, and we
want to keep the two handles distinct to avoid, for example, displaying
handles closed before they're opened.
In policy handle open replies, store the handle name only if the
operation succeeded. We can now do that without parsing the packet
twice.
Have "dissect_nt_policy_hnd()" optionally return, through a pointer, the
protocol tree item for the handle, so that its caller can decorate the
item with the name of the handle - that's done on opens, where we do
that only if the operation succeeds.
