Fix 'access_log none' to prevent following logs being used

The documented behaviour of "access_log none" for preventing logging
using log lines following the directive has not been working in
Squid-3 for some time.

Since the 'none' type does not have a log module associated the entire
switch logic where its abort is checked for was being skipped.
