[PATCH] usbaudio: prevent oops & dead keyboard on usb unplugging while the device is being used

Without this patch, some usb kobjects, which are parents to the usx2y's
kobjects can be freed before the usx2y's. This led to an oops in
get_kobj_path_length() and a dead keyboard, when the usx2y's kobjects
were freed. The patch ensures the correct sequence. Tested ok on
kernel 2.6.12-rc2.
