Remove unnecessary 'none' check from ip6cidr validation

The ip6cidr field does not have a default value of 'none' (unlike aclid),
so checking for != none is unnecessary and could cause confusion if a user
actually tries to set ip6cidr = "none". The GetOk() check is sufficient
to determine if the field has been set.
