Crystal Wood 9cb99c5986 tracing/osnoise: Array printk init and cleanup ...

None of the calls to trace_array_printk_buf() will do anything
if we don't initialize the buffer on instance creation (unless
some other tracer called it), so do that.

Add an osnoise_print() function to facilitate adding debug prints
(without tainting).

Use trace_array_printk() instead of trace_array_printk_buf(), as we're
only writing to the main buffer (of a non-main instance) anyway -- and
trace_array_printk_buf() skips the check to make sure we're not printing
to the global instance.
