[POWERPC] Avoid possible extra of_node_put in axon_msi.c

Browse source

I got this warning from gcc:
arch/powerpc/platforms/cell/axon_msi.c:118: warning: 'tmp' may be used uninitialized in this function

Which turns out to be a false positive, but pointed out that it was
possible for the error path in find_msi_translator() to do an extra
of_node_put on a node.  This fixes it by localising the ref counting
a bit.  As a side effect, the warning goes away.
