rt2800: use RTS/CTS protection instead of CTS-to-self
Change default to RTS/CTS protection. This has a cost of transmitting one more control frame (RTS) however protect us from traffic from hidden node. On station mode will use CTS-to-self if AP will configure that for the network. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
