tcp: Link bhash2 to bhash.
bhash2 added a new member sk_bind2_node in struct sock to link
sockets to bhash2 in addition to bhash.
bhash is still needed to search conflicting sockets efficiently
from a port for the wildcard address. However, bhash itself need
not have sockets.
If we link each bhash2 bucket to the corresponding bhash bucket,
we can iterate the same set of the sockets from bhash2 via bhash.
This patch links bhash2 to bhash only, and the actual use will be
in the later patches. Finally, we will remove sk_bind2_node.
