netfilter: ctnetlink: add timeout and protoinfo to destroy events
DESTROY events do not include the remaining timeout.
Add the timeout if the entry was removed explicitly. This can happen
when a conntrack gets deleted prematurely, e.g. due to a tcp reset,
module removal, netdev notifier (nat/masquerade device went down),
ctnetlink and so on.
Add the protocol state too for the destroy message to check for abnormal
state on connection termination.
Joint work with Pablo.
