powerpc: Use of_node_init() for the fakenode in msi_bitmap.c
This patch uses of_node_init() to initialize the kobject in the fake
node used in test_of_node(), to avoid following kobject warning.
[ 0.897654] kobject: '(null)' (c0000007ca183a08): is not initialized, yet kobject_put() is being called.
