srm: add missing information from "ls queues" command

The 'ls queues' command prints detailed information about the current
status of different queues within the SRM.  The output claims to
show the current status of download (get) requests, but one part of
this output is actually showing 3rd-party copy activity.

This patch fixes the simple typo to show the correct information.
