Subject: [net-next 10/18] i40evf: Move some i40evf_reset_task code to separate function

From: Joe Perches <joe@...ches.com>

The i40evf_reset_task function is a couple hundred lines and it has
a separable block that disables VF.  Move that block to a new
i40evf_disable_vf function to shorten i40evf_reset_task a bit.
