Steven Rostedt 253db536a7 tracing: samples: Initialize trace_array_printk() with the correct function
commit 1b0c192c92 upstream.

When using trace_array_printk() on a created instance, the correct
function to use to initialize it is:

  trace_array_init_printk()

Not

  trace_printk_init_buffer()

The former is a proper function to use, the latter is for initializing
trace_printk() and causes the NOTICE banner to be displayed.
