net: dsa: don't print non-fatal MTU error if not supported

Browse Source 
Commit 72579e14a1 ("net: dsa: don't fail to probe if we couldn't set
the MTU") changed, for some reason, the "err && err != -EOPNOTSUPP"
check into a simple "err". This causes the MTU warning to be printed
even for drivers that don't have the MTU operations implemented.
Fix that.
