net: drv: netdevsim: don't napi_complete() from netpoll
netdevsim supports netpoll. Make sure we don't call napi_complete()
from it, since it may not be scheduled. Breno reports hitting a
warning in napi_complete_done():
WARNING: CPU: 14 PID: 104 at net/core/dev.c:6592 napi_complete_done+0x2cc/0x560
__napi_poll+0x2d8/0x3a0
handle_softirqs+0x1fe/0x710
This is presumably after netpoll stole the SCHED bit prematurely.
