Subject: [net-next 14/15] ice: Use the right function to enable/disable VSI

From: Dave Ertman <david.m.ertman@...el.com>

The ice_ena/dis_vsi should have a single differentiating
factor to determine if the netdev_ops call is used or a
direct call to ice_vsi_open/close.  This is if the netif is
running or not.  If netif is running, use ndo_open/ndo_close.
Else, use ice_vsi_open/ice_vsi_close.
