Subject: [PATCH 3.13.y-ckt 109/121] can: esd_usb2: fix memory leak on disconnect

3.13.11-ckt12 -stable review patch.  If anyone has any objections, please let me know.

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

From: Alexey Khoroshilov <khoroshilov@...ras.ru>

commit efbd50d2f62fc1f69a3dcd153e63ba28cc8eb27f upstream.

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

Found by Linux Driver Verification project (linuxtesting.org).
