[PATCH 2/2] drbd: select CONFIG_NET_HANDSHAKE

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The TLS handshake code is optional and has to be enabled for DRBD:

ERROR: modpost: "tls_handshake_cancel" [drivers/block/drbd/drbd_transport_tcp.ko] undefined!
ERROR: modpost: "tls_server_hello_x509" [drivers/block/drbd/drbd_transport_tcp.ko] undefined!
ERROR: modpost: "tls_client_hello_x509" [drivers/block/drbd/drbd_transport_tcp.ko] undefined!
ERROR: modpost: "tls_get_record_type" [drivers/block/drbd/drbd_transport_tcp.ko] undefined!
ERROR: modpost: "tls_alert_recv" [drivers/block/drbd/drbd_transport_tcp.ko] undefined!

Select the option whenever DRBD is eanbled and rework the dependency in
the symbol so it can be selected more easily.
