[PATCH 5.15 158/279] net: dpaa2-eth: fix use-after-free in dpaa2_eth_remove

[Greg Kroah-Hartman]

From: Pavel Skripkin <paskripkin@xxxxxxxxx>

[ Upstream commit 9b5a333272a48c2f8b30add7a874e46e8b26129c ]

Access to netdev after free_netdev() will cause use-after-free bug.
Move debug log before free_netdev() call to avoid it.

Fixes: 7472dd9f6499 ("staging: fsl-dpaa2/eth: Move print message")
