[for-next][PATCH 2/2] tracing: Make system_callback() function static

[Steven Rostedt]

From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

The system_callback() function in trace_events.c is only used within that
file. The "static" annotation was missed.

Fixes: 5790b1fb3d672 ("eventfs: Remove eventfs_file and just use eventfs_inode")
Reported-by: kernel test robot <lkp@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-kbuild-all/202310051743.y9EobbUr-lkp@xxxxxxxxx/
