[PATCH] bus: arm-cci: release node before breaking child_of_node loop

[Deepak R Varma]

The iterator for_each_available_child_of_node() increments the refcount
of the child node it is processing. Release such a reference when the
loop needs to break due to an error during its execution.
Issue identified using for_each_child.cocci Coccinelle semantic patch.
