vrf: T4191: bugfix for "ip rule" when VRFs are created

We always mangled and worked on the "ip rule" singleton even when nothing
needed to be changed. This resulted in a VRF hickup when the same VRF was added
and removed multiple times.

set interfaces ethernet eth1 vrf foo
set vrf name foo table '1000'

delete interfaces ethernet eth1 vrf
delete vrf

set interfaces ethernet eth1 vrf foo
set vrf name foo table '1000'
commit

broke reachability on eth1 - a reboot was required.

This change will now only alter the ip rule tables once when VRF instances
are created for the first time and will not touch the Kernel "ip rule"
representation afterwards.
