[PATCH] trace/osnoise: Do not use 'main' as variable name

[Guenter Roeck]

gcc 11.x may get a hiccup when encountering 'main' as variable name.

kernel/trace/trace_osnoise.c: In function 'start_kthread':
kernel/trace/trace_osnoise.c:1515:8: error: 'main' is usually a function

Use a different variable name to silence it.
