wifi: cfg80211: Fix validating BSS pointers in __cfg80211_connect_result 

Driver's SME is allowed to fill either BSSID or BSS pointers in struct
cfg80211_connect_resp_params when indicating connect response but a
check in __cfg80211_connect_result() is giving unnecessary warning when
driver's SME fills only BSSID pointer and not BSS pointer in struct
cfg80211_connect_resp_params.

In case of mac80211 with auth/assoc path, it is always expected to fill
BSS pointers in struct cfg80211_connect_resp_params when calling
__cfg80211_connect_result() since cfg80211 must have hold BSS pointers
in cfg80211_mlme_assoc().

So, skip the check for the drivers which support cfg80211 connect
callback, for example with brcmfmac is one such driver which had the
warning:

WARNING: CPU: 5 PID: 514 at net/wireless/sme.c:786 __cfg80211_connect_result+0x2fc/0x5c0 [cfg80211]
