Subject: [PATCH net 2/3] ice: check if VF exists before mode check

From: Michal Swiatkowski <michal.swiatkowski@...el.com>

Setting trust on VF should return EINVAL when there is no VF. Move
checking for switchdev mode after checking if VF exists.

Fixes: c54d209c78b8 ("ice: Wait for VF to be reset/ready before configuration")
