-This fix basically moves the option length check up and also
-corrects an off by one error with it.

-Subject: DHCPv6: Fix a potential read overflow with D6_OPTION_PD_EXCLUDE
-
-dhcpcd only checks that the prefix length of the exclusion
-matches the prefix length of the ia and equals the length of the
-data in the option.
-This could potentially overrun the in6_addr structure.
-
-This is fixed by enforcing RFC 6603 section 4.2 option limits
-more clearly.
-
-Thanks to Maxime Villard <max@m00nbsd.net> for finding this.
