Revert "vdpa/mlx5: Return error on vlan ctrl commands if not supported"

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2169174

Upstream Status: RHEL only

SVQ can not work with vlan filtering and support VLAN in SVQ is not a
high priority now, so need to revert these commit in rhel9.2

This reverts commit e68cd3f.
