[PATCH net-next] net: ipv6: rpl*: Fix strange kerneldoc warnings due to bad header

net/ipv6/rpl_iptunnel.c:15: warning: cannot understand function prototype: 'struct rpl_iptunnel_encap '

The header on the file containing the author copyright message uses
kerneldoc /** opener. This confuses the parser when it gets to

struct rpl_iptunnel_encap {
	struct ipv6_rpl_sr_hdr srh[0];
};

Similarly:

net//ipv6/rpl.c:10: warning: Function parameter or member 'x' not described in 'IPV6_PFXTAIL_LEN'

where IPV6_PFXTAIL_LEN is a macro definition, not a function.

Convert the header comments to a plain /* comment.
