  Log Message:
  -----------
  rest_client: Explicitly set retcode_pv to 0 on error

This avoids any scripting mistakes where:

    * the user does not init $var(http_rc) to 0 prior to rest_get()
    * rest_get() fails (e.g. connection timeout -- web server is down)
    * $var(http_rc) is untouched, yet mistakenly holds 200 from a
      previous (successful) run of the same process
