musb-new: Properly remove a transfer from the schedule on timeout
If a transfer / urb times-out, properly remove it from the schedule, rather then letting it sit on the ep head. This stops the musb code from getting confused and refusing to queue further transfers after a timeout. Tested by unplugging a usb-keyboard, replugging it and doing a usb-reset, before this commit the keyboard would not work after the usb-reset. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
