wlan: Use cfg80211_roamed_bss API to indicate the roaming
After disconnect request, the driver sends disconnect
indication to the kernel and it schedules a workqueue to
process this disconnect event. Now if this workqueue is
delayed and connect request is received before its
scheduled, the disconnect event workqueue reset the
ssid_len of the wdev.
Now as the ssid_len does not match with bss ssid length the
get bss returns NULL and thus roam indication is not sent
to supplicant.
To fix this use cfg80211_roamed_bss to indicate the roaming
and use the ssid and ssid len from driver to get the bss.
