Commit Message

The functions stop_active_transfers and ep_disable are both calling
remove_requests. This functions in both cases will giveback the requests
with status ESHUTDOWN, which also represents an physical disconnection.
For ep_disable this is not true. This patch adds the status parameter to
remove_requests and sets the status to ECONNRESET on ep_disable.
