[PATCH] arch/powerpc/platforms/powermac/pic.c: move of_node_put

From: Julia Lawall <redacted>

It seems better to dereference master before decrementing the reference
count rather than afterwards.

The problem was found using the following semantic match:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
expression n,E;
identifier fld;
iterator I;
statement S;
@@

* of_node_put(n)
... when != n = E
    when != I(n,...) S
* n->fld
// </smpl>
