Maciej Sosnowski f413827747 dca: check against empty dca_domains list before unregister provider ...

commit c419fcfd07 upstream.

When providers get blocked unregister_dca_providers() is called ending up
with dca_providers and dca_domain lists emptied. Dca should be prevented from
trying to unregister any provider if dca_domain list is found empty.
