netlink: correct nlmsg size for multicast notifications
Corrected the netlink message size calculation for multicast group
join/leave notifications. The previous calculation did not account for
the inclusion of both IPv4/IPv6 addresses and ifa_cacheinfo in the
payload. This fix ensures that the allocated message size is
sufficient to hold all necessary information.
This patch also includes the following improvements:
* Uses GFP_KERNEL instead of GFP_ATOMIC when holding the RTNL mutex.
* Uses nla_total_size(sizeof(struct in6_addr)) instead of
nla_total_size(16).
* Removes unnecessary EXPORT_SYMBOL().
Fixes: 2c2b61d2138f ("netlink: add IGMP/MLD join/leave notifications")
