ibmveth: Do not process frames after calling napi_reschedule

Browse source 
[ Upstream commit e95d22c69b2c130ccce257b84daf283fd82d611e ]

The IBM virtual ethernet driver's polling function continues
to process frames after rescheduling NAPI, resulting in a warning
if it exhausted its budget. Do not restart polling after calling
napi_reschedule. Instead let frames be processed in the following
instance.
