From: Yan-Hsuan Chuang <yhchu...@realtek.com>
cfg80211_sta_opmode_change_notify needs a gfp_t flag to hint the nl80211
stack when allocating new skb, but it is called under tasklet context
here with GFP_KERNEL and kernel will yield a warning about it.
Fixes: ff84e7bfe176 ("mac80211: Add support to notify ht/vht opmode
modification.")
