Chenyuan Yang 5a54367a7c net: davicom: fix UAF in dm9000_drv_remove ...

[ Upstream commit 19e65c45a1507a1a2926649d2db3583ed9d55fd9 ]

dm is netdev private data and it cannot be
used after free_netdev() call. Using dm after free_netdev()
can cause UAF bug. Fix it by moving free_netdev() at the end of the
function.

This is similar to the issue fixed in commit
ad297cd2db ("net: qcom/emac: fix UAF in emac_remove").
