Steven Rostedt (Red Hat) 3132e107d6 tracing: Check if tracing is enabled in trace_puts() ...

If trace_puts() is used very early in boot up, it can crash the machine
if it is called before the ring buffer is allocated. If a trace_printk()
is used with no arguments, then it will be converted into a trace_puts()
and suffer the same fate.
