dm thin: update .io_hints methods to not require handling discards last

Removes assumptions about what might follow the discard setup code
(previously the code would return early if discards not enabled).

Makes it possible to add more capabilites to the end of each .io_hints
method (which is the natural thing to do when adding new features).
