qcacmn: Avoid unlink bss in vdev INIT state

When some faulty AP changes the SSID from hidden to non-hidden
or vice versa, then unlink bss and update bss to kernel happens
multiple times. Then when disconnection happens, it causes
abnormal behavior since the bss entry looks corrupted.

So avoid unlink bss in INIT state to avoid corruption
since cfg80211_disconnected() calls
cfg80211_wdev_release_bsses(wdev) already.
