We observe that the condition of chanctx could not be back to
IEEE80211_CHANCTX_REPLACE_NONE occasionally while STA connection.
In this case the state could be IEEE80211_CHANCTX_REPLACE_OTHER, which
fails the check and then creates another chanctx that leads to the next
round of chan_switch failure in cfg80211_check_combinations().
So, modify state to just rule out IEEE80211_CHANCTX_WILL_BE_REPLACED.
