Make printk_safe_flush() safe in NMI context.
nmi_trigger_cpumask_backtrace() can be called in NMI context. For example the
function is called in watchdog_overflow_callback() if the flag of hardlockup
backtrace (sysctl_hardlockup_all_cpu_backtrace) is true and

Make printk_safe_flush() safe in NMI context. And printk_safe_flush_on_panic()
is
folded into this function. The prototype of printk_safe_flush() is changed to
"void printk_safe_flush(bool panic)".
nmi_trigger_cpumask_backtrace() can be called in NMI context. For example the
