cxl: replace loop with for_each_child_of_node(), remove unneeded of_node_put()
Rewrite the cxl_guest_init_afu() loop in cxl_of_probe() to use
for_each_child_of_node() rather than a hand-coded for loop.
Remove the useless of_node_put(afu_np) call after the loop, where it's
guaranteed that afu_np == NULL.
