net: stmmac: don't set own bit too early for jumbo frames

Commit bb4cf260a322 ("stmmac: first frame prep at the end of xmit
routine") overlooked jumbo frames when re-ordering the code, and as a
result the own bit was not getting set anymore for the first jumbo frame
descriptor. Commit 1b969db2a67e ("net: stmmac: Set OWN bit for jumbo
frames") tried to fix this, but now the bit is getting set too early and
the DMA may start while we are still setting up the remaining descriptors.
And with the chain mode the own bit remains still unset.

Fix by setting the own bit at the end of xmit also with jumbo frames.
