xentrace: fix lost records resume

Reorder the SCHED_SWITCH trace before the runstate change trace to fix
a problem with the lost records "resume" code.

Namely: The "lost records" trace includes the currently running
process.  But during SCHED_SWITCH, it reads the wrong value, confusing
xenalyze.  Making sure there are no trace records between runstate
change trace and the actual context switch fixes it.
