* create with refcount 1
* make op_release() decrement and free if zero (i.e. old put_op()
has become that).
* mark when submitter has given up waiting; from that point nobody
else can move between the lists, change state, etc.
* have daemon read/write_iter grab a reference when picking op
and *always* give it up in the end
* don't put into hash until we know it's been successfully passed to
daemon
* move op->lock _lower_ than htab_in_progress_lock (and make sure
to take it in purge_inprogress_ops())

There was previously MAX_ALIGNED_DEV_REQ_(UP|DOWN)SIZE macros which
evaluated to MAX_DEV_REQ_(UP|DOWN)SIZE+8. As it is unclear what this is
for, other than creating a situation where we accept more data than we
can parse, it is removed.
