lib: Stop potential uninitialized memory access
VRF_UNKNOWN = MAX_INT16_T
The vrf macros to determine where in the bitmap something belongs
assume that the valid values of a vrf are 0 - (MAX_INT16 - 1)
so when they attempt to determine where to look in the bitmap
for VRF_DEFAULT, we can get invalid reads of memory.
This happens because bgp can create vrf's with VRF_UNKNOWN
when we get configuration for a vrf before we've been actually
created in zebra.
