sunliming aef54851bf x86/traceponit: Fix comment about irq vector tracepoints
Commit:

  4b9a8dca0e ("x86/idt: Remove the tracing IDT completely")

removed the 'tracing IDT' from arch/x86/kernel/tracepoint.c,
but left related comment. So that the comment become anachronistic.
Just remove the comment.
