wifi: rt2x00: disable RTS threshold for rt2800 by default
rt2800 has a lot of registers to control the RTS enable/disable
status for different rates. And the driver control them via
rt2800_set_rts_threshold(). When RTS was disabled in user
interface, this function won't be called at all. This means that
the RTS is still 'on' for CCK and OFDM rates. So we'd better to
disable them by default because it should be like this. The RTS
for HT20 and HT40 is already default off so we don't need to
touch them. If we toggle the RTS status, these register bits
will be enable/disable again by rt2800_set_rts_threshold().
