intel: error_decode: add an option to decode all buffers 

The kernel reports workaround batch buffers, but we're not presenting
them currently. Also they might not be useful for debugging purely
userspace driver issues, when problems arise because of interactions
between kernel & userspace drivers, it's nice to be able to decode
them.
