Fix dangling reference in l2fib_scan(...)

Deleting a bihash kvp frees the bucket's backing storage when the
bucket reference count reaches zero. l2fib_scan MUST check for that
condition, and stop scanning the bucket if it occurs. One of the L2
FIB extended "make test" vectors caused this issue 100% of the time.
