SVN rev 188570 on 2009-02-13 10:04:59Z by scottl
In the case that the probe has determined that it can't query the device for
a serial number, fall through to the next case so that initial negotiation
still happens. Without this, devices were showing up with only 1 available
tag opening, leading to observations of very poor I/O performance.
This should fix problems reported with VMWare Fusion and ESX. Early
generation MPT-SAS controllers with SATA disks might also be affected.
HP CISS controllers are also likely affected, as are many other
pseudo-scsi disk subsystems.
