rubocop: cleanup Style/GuardClause issue

filters/need_kconfig.rb:53:5: C: Style/GuardClause: Use a guard clause (raise Job::SyntaxError, "Wrong syntax of kconfig setting: #{expected_kernel_versions}" if match.nil? || match[:kernel_tag].nil?) instead of wrapping the code inside a conditional expression.
    if match.nil? || match[:kernel_tag].nil?
