wil6210: store bss object and use cfg80211_connect_bss()
In a fast disconnect/connect sequence, cfg80211_connect_result() can
fail to find the bss object which the driver is connecting to. Detailed
sequence of events:
* Driver is connected in STA mode
* Disconnect request arrives from user space. Driver disconnects and
calls cfg80211_disconnected() which adds new event to the
cfg80211_wq worker thread
* Connect request arrives from user space. cfg80211_connect() stores
ssid/ssid_len and calls rdev_connect()
* __cfg80211_disconnected() runs in worker thread and zero
wdev->ssid_len
* Connect succeeds. Driver calls cfg80211_connect_result() which fails
to find the bss because wdev->ssid_len is zero
To overcome this, upon connect request, store the bss object in the
driver and upon connect completion pass it to kernel using
cfg80211_connect_bss().
