Currently, most of the rib(9) KPI does not use rnh pointers, using
fibnum and family parameters to determine the rib pointer instead.
This works well except for the case when we initialize new rib pointers
during fib growth.
In that case, there is no mapping between fib/family and the new rib,
as an entirely new rib pointer array is populated.
Address this by delaying fib algo initialization till after switching
to the new pointer array and updating the number of fibs.
Set datapath pointer to the dummy function, so the potential callers
won't crash the kernel in the brief moment when the rib exists, but
no fib algo is attached.
This change allows to avoid creating duplicates of existing rib functions,
with altered signature.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
