hw/scsi/lsi53c895a: fix memory leak in lsi_scsi_realize()
Address a memory leak bug in the usages of timer_del().
The issue arises from the incorrect use of the ambiguous timer API
timer_del(), which does not free the timer object. The LeakSanitizer
report this issue during fuzzing. The correct API timer_free() freed
the timer object instead.
