[ 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().
Fixes: 248122212f68 ("net: mvpp2: use device_*/fwnode_* APIs instead of of_*")
