[ Upstream commit 71f0891c84dfdc448736082ab0a00acd29853896 ]
In each iteration fwnode_for_each_available_child_node() bumps a reference counting of a loop variable followed by dropping in on a next iteration,
Since in error case the loop is broken, we have to drop a reference count by ourselves. Do it for port_fwnode in error case during ->probe().
