Subject: dpaa_eth: remove netdev_err() for user errors

Git-commit: 1f722e19a2648c4310d6f3443558549edaca4081
Patch-mainline: v5.5-rc1
References: bsc#1174550

User reports that an application making an (incorrect) call to
restart AN on a fixed link DPAA interface triggers an error in
the kernel log while the returned EINVAL should be enough.
