lib: fix creation of pre-provisioned VRFs

Browse Source 
If we configure a VRF that doesn't match any device in the kernel, we'll
fall in the first case of the vrf_get() function. In this function,
a vrf structure is callocated and it's vrf_id is never set explicitly,
which means it's set to zero (the vrf-id of the default VRF). When this
happens, commands like "router-id A.B.C.D vrf ..." will act on the
default VRF and not on the pre-provisioned VRF.  To fix this, always
set the vrf_id of pre-provisioned VRFs to VRF_UNKNOWN.
