wlan: Always update the bss in cfg80211 before connection.

In wlan_hdd_cfg80211_inform_bss, cfg80211_inform_bss is called
only if bss is not present in kernel bss list. This might leads
to a scenario that bss is present when checked but get expired
before connect result are sent to cfg80211 resulting the kernel
not entering in connected state.

Always call cfg80211_inform_bss before sending connect result to
update the bss list in kernel. This updates the bss in the list
and increase its expiry time to IEEE80211_SCAN_RESULT_EXPIRE time.
