[ Upstream commit b44c0e7fef51ee7e8ca8c6efbf706f5613787100 ]
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.
