monitor: add assignment check for json_echo

When --echo and --json is specified and native syntax is read, only the
last instruction is printed. This happens because the reference to the
json_echo is reassigned each time netlink_echo_callback is executed for
an instruction to be echoed.

Add an assignment check for json_echo to avoid reassigning it.
