[SCSI] ips: fix soft lockup during reset initialization

  Resetting the adapter causes the ServeRAID driver to exceed the max time
  allowed by the softlock watchdog.  Resetting the hardware can easily require
  30 or more seconds.  To avoid the

	"BUG: soft lockup detected on CPU#0!"

  result, this patch adds a touch_nmi_watchdog() to the driver's MDELAY macro.
