CLI: fix segfault when browsing an empty history
When one starts VPP, types a command, presses up rather than enter, then types a new command, unix_cli_line_process_one() segfaults. This is due to cf->cursor not being reset upon pressing up if the history is empty. Change-Id: Ie503f20a9cb551e735abb8b0f4feb8c0006d2b61 Signed-off-by: Yoann Desmouceaux <ydesmouc@cisco.com>
