ice: Fix issue with VF reset and multiple VFs support on PFs
This patch fixes issues with VF queues being disabled, and VF netdev network carrier being lost after reset. Basically, we need to check if VF is enabled, and queue configured in reset_all_vfs flow, and disable/enable those queues appropriately whenever the function is called after Global/CORER/PFR reset/rebuild/replay.
