This is to suppress prink() messages, which prior to 42a0bb3f7138 ("printk/nmi: generic solution for safe printk in NMI"), were unsafe in NMI context. We don't need to do this anymore, remove the flag. printk() messages are batched in a per-cpu buffer and printed via irq-work, or a call back from panic().
