Fix potential NULL pointer dereference in dsl_dataset_promote_check()
If the `list_head()` returns NULL, we dereference it, right before we
check to see if it returned NULL.

We have defined two different pointers that both point to the same
thing, which are `origin_head` and `origin_ds`. Almost everything uses
`origin_ds`, so we switch them to use `origin_ds`.

We also promote `origin_ds` to a const pointer so that the compiler
verifies that nothing modifies it.

Coverity complained about this.
