[PATCH] arch: sparc: add missing of_node_put before return

[Qing Wang]

From: Wang Qing <wangqing@xxxxxxxx>

Fix following coccicheck warning:
WARNING: Function "for_each_node_by_type" 
should have of_node_put() before return.

Early exits from for_each_node_by_type should decrement the
node reference counter.
