Subject: [PATCH] Report an error when file transfers are disabled

This commit sends back a VD_AGENT_FILE_XFER_STATUS_ERROR to clients which
try to transfer files when the agent disabled file transfers (for example
because there is no valid destination directory for the transferred files).

(cherry picked from commit 9ea18740b8cf4466ebd2f6bca42d1d70dd0ba01c)
