[PATCH BlueZ] device: fix advertising data UUIDs ignored when Cache = yes

When [GATT] Cache = yes is set in configuration BlueZ does not use
cached UUIDs for the list of service UUIDs. However, it doesn't clear
the in-memory list of UUIDs received from advertising data, so when
a device is scanned, connected and disconnected, the internal state
still reflects that the UUIDs from the advertising data have already
been handled. device_add_eir_uuids() ignored the UUIDs from the
advertising data because both dev->le_state.svc_resolved == true and
dev->eir_uuids still contains the UUIDs from the previous scan session.

This fixes the issue by resetting both le_state.svc_resolved and
eir_uuids when the device is disconnected.
