Better error message when using --mirror in existing workspace

If repo init is run with the --mirror option, repo checks if there
is already a workspace initialized in the current location, and if
so, exits with an error message:

  --mirror not supported on existing client

This error can cause confusion; the users do not understand what
is wrong and what they need to do to fix it.

Change the error message to make it a bit clearer.
