In a few places we have IP6_EXTHDR_GET() left in upper layer protocols. The IP6_EXTHDR_GET() macro might perform an m_pulldown() in case the data fragment is not contiguous. Convert these last remaining instances into m_pullup()s instead. In CARP, for example, we will a few lines later call m_pullup() anyway, the IPsec code coming from OpenBSD would otherwise have done the m_pullup() and are copying the data a bit later anyway, so pulling it in seems no better or worse. Note: this leaves very few m_pulldown() cases behind in the tree and we might want to consider removing them as well to make mbuf management easier again on a path to variable size mbufs, especially given m_pulldown() still has an issue not re-checking M_WRITEABLE().
