firewire: Preserve response data alignment bug when it is harmless
Recently, a bug having to do with the alignment of transaction response data was fixed. However, some apps such as libdc1394 relied on the presence of that bug in order to function correctly. In order to stay compatible with old versions of those apps, this patch preserves the bug in cases where it is harmless to normal operation (such as the single quadlet read) due to a simple duplication of data. This guarantees maximum compatability for those users who are using the old app with the fixed kernel.
