ShellPkg/cd: Do not print the destination dir when CD exits

Before the "cd fs0:dir" fix, CD only prints destination directory
when the destination contains ":".
However, the "cd fs0:dir" fix changed CD to always print destination
directory.

This patch changes CD to never print destination directory.
