firewalldb: update kvdb assertEqualActions

The upcoming commit will update the `AddActionReq` struct to include an
extra field which the `kvdb` actions store will ignore. Therefore the
`assertEqualActions` for the `kvdb` version will need to be update to
ignore this field. In preparation for that change, we also do another
optimization of the `assertEqualActions` function under kvdb builds, to
not mutate the passed action references.
