staticd : Added the warning log for route when VRF is not ready.

During the yangification of staticd, refactoring of code
around static_hold_route data struct has been done, In this
context warning log message when VRF is not ready had been
removed. This should not be removed, adding it back.

I have missed one MPLS validation too, adding it back.
