Building with 'make W=1' shows a harmless -Wempty-body warning:

drivers/scsi/aic94xx/aic94xx_init.c: In function 'asd_free_queues':
drivers/scsi/aic94xx/aic94xx_init.c:858:62: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
  858 |                 ASD_DPRINTK("Uh-oh! Pending is not empty!\n");

Change the empty ASD_DPRINTK() macro to no_printk(), which avoids this
warning and adds format string checking.
