[PATCH] mac80211: adjust the replace_state of ieee80211_find_chanctx()

[Ryder Lee]

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.
