[PATCH 5.17 027/146] ice: allow creating VFs for !CONFIG_NET_SWITCHDEV

[ Upstream commit aacca7a83b9753c562395ef328352dfd8c003c59 ]

Currently for !CONFIG_NET_SWITCHDEV kernel builds it is not possible to
create VFs properly as call to ice_eswitch_configure() returns
-EOPNOTSUPP for us. This is because CONFIG_ICE_SWITCHDEV depends on

Change the ice_eswitch_configure() implementation for
!CONFIG_ICE_SWITCHDEV to return 0 instead -EOPNOTSUPP and let
ice_ena_vfs() finish its work properly.
