acc_ramp: Increase log level of some messages

Right now, it's impossible to see any ACC Ramping information unless RSL
category is set to DEBUG. Barring and Allowing Access Control Class is
an important event which should be printed in most cases.

Increase log levels of messages printed during some error conditions to
be handled as errors.
