Warner Losh e35816c1c9 mpr/mps: Fix a race in diagnostic reset ... There's a small race in freezing the simq when performing a diagnostic reset. During this time, a transaction can slip through and encounter the target id of 0. If we're still in diagnostic reset when we detect this, return a CAM_DEVICE_NOT_THERE status. Instead, freeze the queue and return a requeue status, similar to what we do when we're resetting a target and a transaction get here. The race is unavoidable due to separate locks for queue and SIM, but easy enough to detect and make harmless.
