Subject: ibmvnic: remove duplicate napi_schedule call in open function
From: Lijun Pan <lijunp213@xxxxxxxxx>
commit 7c451f3ef676c805a4b77a743a01a5c21a250a73 upstream.
Remove the unnecessary napi_schedule() call in __ibmvnic_open() since
interrupt_rx() calls napi_schedule_prep/__napi_schedule during every
receive interrupt.
Fixes: ed651a10875f ("ibmvnic: Updated reset handling")
