net: rpl: fix rpl header size calculation
This patch fixes a missing 8 byte for the header size calculation. The
ipv6_rpl_srh_size() is used to check a skb_pull() on skb->data which
points to skb_transport_header(). Currently we only check on the
calculated addresses fields using CmprI and CmprE fields, see:
https://www.rfc-editor.org/rfc/rfc6554#section-3
there is however a missing 8 byte inside the calculation which stands
for the fields before the addresses field. Those 8 bytes are represented
by sizeof(struct ipv6_rpl_sr_hdr) expression.
Fixes: 8610c7c6e3bd ("net: ipv6: add support for rpl sr exthdr")
