Hangyu Hua 55e2013a22 usb: misc: fix improper handling of refcount in uss720_probe()
commit 0a96fa640d upstream.

usb_put_dev shouldn't be called when uss720_probe succeeds because of
priv->usbdev. At the same time, priv->usbdev shouldn't be set to NULL
before destroy_priv in uss720_disconnect because usb_put_dev is in
destroy_priv.

Fix this by moving priv->usbdev = NULL after usb_put_dev.
