dsl_scan: close errorscrub cursor on pause

If the cursor were ever to actively hold resources, not finalising it
would mean leaking those resources whenever the scrub is paused.

The cursor is already reinitialized from the stored serialized form
if/when it is resumed, so there's nothing we need from the old one, just
to release it.
