[Intel-wired-lan] [PATCH 1/2] ice: allow creating VFs when !CONFIG_ICE_SWITCHDEV

[Vincent Chen]

Currently ice_eswitch_attach_vf() is called unconditionally in
ice_start_vfs(), which causes VF creation to fail when CONFIG_ICE_SWITCHDEV
is not defined.

Fix this by adding switchdev mode checks at the call sites before
calling ice_eswitch_attach_vf(), consistent with how
ice_eswitch_attach_sf() is already handled in ice_devlink_port_new().
This is similar to commit aacca7a83b97 ("ice: allow creating VFs for
!CONFIG_NET_SWITCHDEV") which fixed the same issue for the previous
ice_eswitch_configure() API.
