HS 2.0: Try to use same BSS entry for storing GAS results

Browse source 
Commit 17b8995cf5 ('Interworking: Try to
use same BSS entry for storing GAS results') added a mechanism to try to
pair GAS request and response to a single BSS entry to cover cases where
multiple BSS entries may exists for the same BSSID. However, that commit
did not cover the Hotspot 2.0 ANQP elements. Extend this mechanism to
all ANQP elements. This can help in cases where information in the
Hotspot 2.0 specific ANQP elements got lost if a hidden SSID or some
other reason of duplicated BSS entries was present while doing ANQP
fetches.
