If AP change its status from hidden to broadcasting SSID in its beacon
kernel drop the beacon entry as its confusing. Now during connection
driver try to update the entry in kernel and it fails and as kernel drop
the beacon the connection fails.
To fix this detect if AP changed its ssid type from hidden to
broadcasting and unlink the old bss from kernel in that case.
