Subject: i40evf: remove flush_scheduled_work call in i40evf_remove
Patch-mainline: v4.16-rc1
Git-commit: a558566befaae03f64fd0e4271e6e4d17514644c
References: bsc#1101816 FATE#325147 FATE#325149

flush_schedule_work blocks until completion of all scheduled
work items in global work-queue. This can cause deadlock in some
cases. i40evf_remove() cleans up necessary work items with
cancel_delayed_work_sync and cancel_work_sync. This fix removes
flush_schedule_work call inside i40evf_remove().
