s390/qeth: let isolation mode override HW offload restrictions

Browse source 
When a device is configured with ISOLATION_MODE_FWD, traffic never goes
through the internal switch. Don't apply the offload restrictions in
this case.

Fixes: c619e9a6f5 ("s390/qeth: don't use restricted offloads for local traffic")
