Add missing usb_free_urb on failure path after usb_alloc_urb.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @km exists@ local idexpression e; expression e1,e2,e3; type T,T1; identifier f; @@
* e = usb_alloc_urb(...) ... when any when != e = e1 when != e1 = (T)e when != e1(...,(T)e,...) when != &e->f if(...) { ... when != e2(...,(T1)e,...) when != e3 = e when forall ( return <+...e...+>; | * return ...; ) } // </smpl>
