[PATCH 3.16.y-ckt 034/168] can: esd_usb2: fix memory leak on disconnect

[Luis Henriques]

3.16.7-ckt3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexey Khoroshilov <khoroshilov at ispras.ru>

commit efbd50d2f62fc1f69a3dcd153e63ba28cc8eb27f upstream.

It seems struct esd_usb2 dev is not deallocated on disconnect. The patch adds
the missing deallocation.
