[PATCH] netlink: update outdated comment

[PATCH] netlink: update outdated comment

[Kexin Sun]

The function netlink_clear_multicast_users() was removed as unused
in commit 2173f8d953e7 ("netlink: cleanup tap related functions").
Update the comment in netlink_change_ngroups() to remove the stale
reference, replacing it with a general description of the behavior
while preserving the warning.
