Before this change, the FDR BufferQueue iterator could access oob memory due to checks of the form `!Buffers[Offset].Used && Offset != Max`. This allows access to `Buffers[Max]`, which is past the end of the `Buffers` array. This can lead to crashes when that memory is not mapped. Fix this by testing `Offset != Max` first.
