Fix the following sparse warning:
samples/trace_printk/trace-printk.c:7:6: warning: symbol
'trace_printk_test_global_str' was not declared. Should it be static?
samples/trace_printk/trace-printk.c:10:6: warning: symbol
'trace_printk_test_global_str_irq' was not declared. Should it be
static?
samples/trace_printk/trace-printk.c:13:6: warning: symbol
'trace_printk_test_global_str_fmt' was not declared. Should it be
static?
