andre d4e3412583 Fix an out of bounds write during the initialization of the PF_INET protocol
family to the ip_protox[] array.  The protocol number of IPPROTO_DIVERT is
larger than IPPROTO_MAX and was initializing memory beyond the array.
Catch all these kinds of errors by ignoring protocols that are higher than
IPPROTO_MAX or 0 (zero).

Add more comments ip_init().
