Now that the check is fixed, it turn out there is a related problem in
the same function. If the device is in the managed mode and disconnects
from an AP due to a low signal, attempts to reassociate by setting the
same ESSID fail:
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device wlan0 ; Operation already in progress.
It happens because wdev->auth_bsses[i] is not set to NULL.
cfg80211_sme_disassoc() can do it, but not if wdev->conn->state is
CFG80211_CONN_IDLE.
Either cfg80211_sme_disassoc() or __cfg80211_send_disassoc() should
unset wdev->auth_bsses[i] for the management mode.
