[PATCH] bus: qcom: Put child node before return

[Pan Bian]

Put child node before return to fix potential reference count leak.
Generally, the reference count of child is incremented and decremented
automatically in the macro for_each_available_child_of_node() and should
be decremented manually if the loop is broken in loop body.
