ixgbevf: support RSS config on x550

On x550, there're separate registers provided for VF RSS while on the other
10G NICs, for example, 82599, VF and PF share the same registers.
This patch lets x550 use the VF specific registers when doing RSS configuration
on VF. The behavior of other 10G NICs doesn't change.
