Subject: [PATCH net-next] net: stmmac: remove unused get_addr() callback
The last caller of the stmmac_desc_ops::get_addr() callback was removed
a while ago, so remove the unused callback.
Note that the callback also only gets half the descriptor address on
systems with 64-bit descriptor addresses, so that should be fixed if it
needs to be resurrected later.
Fixes: ec222003bd948de8f3 ("net: stmmac: Prepare to add Split Header support")
