Use the CPU and task name captured at printk() time from nbcon_write_context instead of querying the current execution context. This provides accurate information about where the message originated, rather than where netconsole happens to be running. For CPU, use wctxt->cpu instead of raw_smp_processor_id(). For taskname, use wctxt->comm directly which contains the task name captured at printk time. This change ensures netconsole outputs reflect the actual context that generated the log message, which is especially important when the console driver runs asynchronously in a dedicated thread.
