[ALSA] usbaudio - Fix kobject_add() error at reconnection

Browse Source 
Fixed the error from kobject_add() at reconnection the usb audio device.
This happens when an app keeps opening a device while the device is
replugged, due to the confliction of the internal bookkept index and
the really empty slot.
