net: mv643xx_eth: fix an OF node reference leak

Browse source

[ Upstream commit ad5c318086 ]

Current implementation of mv643xx_eth_shared_of_add_port() calls
of_parse_phandle(), but does not release the refcount on error. Call
of_node_put() in the error path and in mv643xx_eth_shared_of_remove().

This bug was found by an experimental verification tool that I am
developing.
