SYSLINK: procmgr - Removed extra ducati_destroy call from proc4430_destroy

In proc4430, ducati_destroy() is called from both proc4430_destroy() and
proc4430_stop().  Since ducati_setup() is called from proc4430_start(), the
call to ducati_destroy() in proc4430_destroy() is invalid.  It generates a
crash.
