[PATCH 2/2] tracing/osnoise: add printf attribute to osnoise_print

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

gcc points out that tne newly added function uses printf style arguments
and should get an attribute to allow verifying the format strings for
its callers:

kernel/trace/trace_osnoise.c: In function 'osnoise_print':
kernel/trace/trace_osnoise.c:96:17: error: function 'osnoise_print' might be a candidate for 'gnu_printf' format attribute [-Werror=suggest-attribute=format]
   96 |                 trace_array_vprintk(tr, _RET_IP_, fmt, ap);
      |                 ^~~~~~~~~~~~~~~~~~~

Add the attribute as suggested
