Use network epoch to protect local IPv4 addresses hash.
The modification to the hash are already naturally locked by
in_control_sx. Convert the hash lists to CK lists. Remove the
in_ifaddr_rmlock. Assert the network epoch where necessary.
Most cases when the hash lookup is done the epoch is already entered.
Cover a few cases, that need entering the epoch, which mostly is
initial configuration of tunnel interfaces and multicast addresses.
