net: Add comment that early_demux can change via sysctl
Twice patches trying to constify inet{6}_protocol have been reverted:
39294c3df2a8 ("Revert "ipv6: constify inet6_protocol structures"") to
revert 3a3a4e3054137 and then 03157937fe0b5 ("Revert "ipv4: make
net_protocol const"") to revert aa8db499ea67.
Add a comment that the structures can not be const because the
early_demux field can change based on a sysctl.
