[PATCH] powerpc/kexec_file: Add of_node_put() before goto

Fix following coccicheck warning:
./arch/powerpc/kexec/file_load_64.c:698:1-22: WARNING: Function
for_each_node_by_type should have of_node_put() before goto

Early exits from for_each_node_by_type should decrement the
node reference counter.
