Greg Kroah-Hartman 00477cab05 nfc: pn533: properly drop the usb interface reference on disconnect 
commit 12133a483d upstream.

When the device is disconnected from the driver, there is a "dangling"
reference count on the usb interface that was grabbed in the probe
callback.  Fix this up by properly dropping the reference after we are
done with it.
