tracing: samples: Initialize trace_array_printk() with the correct function
commit 1b0c192c92ea1fe2dcb178f84adf15fe37c3e7c8 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.
