[PATCH] sim: fix unused cpu_nr warnings

[Mike Frysinger <vapier@gentoo.org>]

The trace_option_handler() function only uses cpu_nr when the
SIM_HAVE_ADDR_RANGE define is enabled.  So move the decl down
to where the code exists.  Otherwise GCC warns:
sim-trace.c: In function 'trace_option_handler':
sim-trace.c:236: warning: unused variable 'cpu_nr'

	* sim-trace.c (trace_option_handler): Move cpu_nr decl behind
	the SIM_HAVE_ADDR_RANGE define.
