net: ethernet: stmmac: fix of-node and fixed-link-phydev leaks
Make sure to deregister and free any fixed-link phy registered during
probe on probe errors and on driver unbind by adding a new glue helper
function.
Drop the of-node reference taken in the same path also on late probe
errors (and not just on driver unbind) by moving the put from
stmmac_dvr_remove() to the new helper.
Fixes: 277323814e49 ("stmmac: add fixed-link device-tree support")
Fixes: 4613b279bee7 ("ethernet: stmicro: stmmac: add missing of_node_put
after calling of_parse_phandle")
