[PATCH v2 net-next] net: remove outdated comment for ipv4 and ipv6 protocol handler

[baker.kernel@gmail.com]

From: Baker Zhang <Baker.kernel@gmail.com>

since f9242b6b28d61295f2bf7e8adfb1060b382e5381
inet: Sanitize inet{,6} protocol demux.

there are not pretended hash tables for ipv4 or
ipv6 protocol handler.

V1:
inet_add_protocol/inet_del_protocol and inet6_del_protocol
are very simple in current version.

so I remove the outdated comment instead of fixing them,
just like inet6_add_protocol.

V2:
Add summary line in parens.
