Julia Lawall 734c299282 drivers/dma: Correct NULL test
cohd_fin has already been verified not to be NULL, so the argument to
BUG_ON cannot be true.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
expression *x;
expression e;
identifier l;
@@

if (x == NULL || ...) {
    ... when forall
    return ...; }
... when != goto l;
    when != x = e
    when != &x
*x == NULL
// </smpl>
