ALSA: ac97: Fix of-node refcount unbalance
commit 31d2350d602511efc9ef626b848fe521233b0387 upstream.
ac97_of_get_child_device() take the refcount of the node explicitly
via of_node_get(), but this leads to an unbalance. The
for_each_child_of_node() loop itself takes the refcount for each
iteration node, hence you don't need to take the extra refcount
again.
