[44net] amprgw router bug fixed

I just found and fixed a bug in the router where it would occasionally reject a valid destination as being an encap-to-encap route and discard the packet. Detail: Rob's address-mask-and-index scheme with the huge global addresses array only works if you FIRST check that the address is on network 44. Oops. Anyway, I restarted the packet errors tallys so they won't show the erroneous results of this bug. - Brian
