fib: fix urpf_itfs vector overflow

When removing duplicates in urpf_itfs vector we search for the 1st next
different entry in the vector, but the loop test is in the wrong order:
(urpf->furpf_itfs[i] == urpf->furpf_itfs[j]
  && j < vec_len(urpf->furpf_itfs))
We must check for overflow before checking equality.

Type: fix
