fib_trie: Minor cleanups to fib_table_flush_external
This change just does a couple of minor cleanups on fib_table_flush_external. Specifically it addresses the fact that resize was being called even though nothing was being removed from the table, and it drops an unecessary indent since we could just call continue on the inverse of the fi && flag check.
