Backport 83e2ec3 from #84908.

Fix incorrect device address reported in the LE Periodic
Advertising Sync Established event when using Periodic
Advertiser List.

During Extended Scanning there can be an ADV_EXT_IND PDU
received between currently being received ADV_EXT_IND PDU
and AUX_ADV_IND PDU; if the one received between has an
address match then incorrectly the Periodic Synchronization
was established to the device whos AUX_ADV_IND PDU is being
received. Fix by storing the auxiliary context that has the
address match and compare with it when matching the SID in
SyncInfo of AUX_ADV_IND PDU being received prior to creating
the synchronization.
