[PATCH] usb: storage: stop all current urbs when device is disconnected

[Ravi Babu <ravibabu@xxxxxx>]

When the scsi mass storage device is disconnected, the current urbs
queued to hcd driver must be cancelled, otherwise the current urbs
are pending at hcd driver and the active urb programmed at host
controller will never be completed. The class driver shall dequeue
or cancel all the urb request submitted to hcd once the device is
disconnected and no longer exits.
