Remove named_validate_dnssec update step

Browse Source 
The upgrade step used to add "dnssec-validation no" to named.conf IFF
named.conf did not contain "dnssec-validation" option at all. The
option has been moved to 'ipa-options-ext.conf' in IPA 4.8.7. The function
only removes the upgrade state.
