Re: [PATCH ghak25 v4 1/3] audit: tidy and extend netfilter_cfg x_tables and ebtables logging

NETFILTER_CFG record generation was inconsistent for x_tables and ebtables configuration changes. The call was needlessly messy and there were supporting records missing at times while they were produced when not requested. Simplify the logging call into a new audit_log_nfcfg call. Honour the audit_enabled setting while more consistently recording information including supporting records by tidying up dummy checks. Add an op= field that indicates the operation being performed (register or replace). Here is the enhanced sample record: type=NETFILTER_CFG msg=audit(1580905834.919:82970): table=filter family=2 entries=83 op=replace Generate audit NETFILTER_CFG records on ebtables table registration. Previously this was being done for x_tables registration and replacement operations and ebtables table replacement only.
