sound/soc/fsl/p1022_ds.c: add missing of_node_put
 
dma_channel_np has been accessed at this point, so decrease its reference
count before leaving the function.

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

// <smpl>
@@
identifier x;
expression E1!=0,E2,E3,E4;
statement S;
iterator I;
@@

(
if (...) { ... when != of_node_put(x)
               when != x = E3
               when != E3 = x
*  return ...;
 }
... when != x = E2
    when != I(...,x,...) S
if (...) { ... when != x = E4
 of_node_put(x); ... return ...; }
)
// </smpl>
