Rusty Russell 9b8fe618f6 pay: remove cmd pointer from htlc_out.
Maintaining it was always fraught, since the command could go away
if the JSON RPC died.  Most recently, it was broken again on shutdown
(see below).

In future we may allow pay commands to block on previous payments, so
it won't even be a 1:1 mapping.  Generalize it: keep commands in a
simple list and do a lookup when a payment fails/succeeds.
