net/mlx4: Don't disable vxlan offloads under DMFS-A0 optimized steering 

Except for VXLAN steering rules, all offloads should work as they were
under plain DMFS mode. Fix that by enabling all the offloads under
DMFS-A0 mode, except for VXLAN steering rules.

Fixes: d57febe1a4 "net/mlx4: Add A0 hybrid steering"
