    Bluetooth: btintel: Check dsbr size from EFI variable

    Since the size of struct btintel_dsbr is already known, we can just
    start there instead of querying the EFI variable size. If the final
    result doesn’t match what we expect also fail. This fixes a stack buffer
    overflow when the EFI variable is larger than struct btintel_dsbr.
