net80211: fix ieee80211_htrateset setup, return EINVAL for an unsupported
ucast/mcast/mgmt HT rate. - Init global ieee80211_htrateset only once; neither ic_htcaps nor ic_txstream is changed when device is attached; - Move global ieee80211_htrateset structure to ieee80211com; there was a possible data race when more than 1 wireless device is used simultaneously; - Discard unsupported rates in ieee80211_ioctl_settxparams(); otherwise, an unsupported value may break connectivity (actually, 'ifconfig wlan0 ucastrate 8' for RTL8188EU results in immediate disconnect + infinite 'device timeout's after it). Tested with: - Intel 6205, STA mode. - RTL8821AU, STA mode. Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D9871
