*: call if_init()/if_terminate() from vrf_init()/vrf_terminate()

Later, an interface will belong to a specific VRF, and the interface
initialization will be a part of the VRF initialization. So now call
if_init() from vrf_init(), and if_terminate() from vrf_terminate().

Daemons have the according changes:
- if if_init() was called or "iflist" was initialized, now call
  vrf_init() instead;
- if if_terminate() was called or "iflist" was destroyed, now call
  vrf_terminate() instead.
