net: typos in comments in include/linux/igmp.h

There are typos in comments in include/linux/igmp.h: 83 #define IGMP_HOST_MEMBERSHIP_QUERY 0x11 /* From RFC1112 */ 84 #define IGMP_HOST_MEMBERSHIP_REPORT 0x12 /* Ditto */ [snip] 88 #define IGMPV2_HOST_MEMBERSHIP_REPORT 0x16 /* V2 version of 0x11 */ 89 #define IGMP_HOST_LEAVE_MESSAGE 0x17 90 #define IGMPV3_HOST_MEMBERSHIP_REPORT 0x22 /* V3 version of 0x11 */ The line 88 and 90 are about REPORT messages. The IGMP_HOST_MEMBERSHIP_REPORT (IGMP V1) value is 0x12. So the comment on line 88 must be /* V2 version of 0x12 */, and the comment on line 90 must be /* V3 version of 0x12 */.
