From: Lijun Pan <lijunp213@xxxxxxxxx>
commit d3a6abccbd272aea7dc2c6f984bb5a2c11278e44 upstream.
During adapter reset, do_reset/do_hard_reset calls ibmvnic_open(),
which will calls napi_schedule if previous state is VNIC_CLOSED
(i.e, the reset case, and "ifconfig down" case). So there is no need
for do_reset to call napi_schedule again at the end of the function
though napi_schedule will neglect the request if napi is already
scheduled.
Fixes: ed651a10875f ("ibmvnic: Updated reset handling")
