[RELENG_7] SBP Drives not recognized

[Sean Bruno]

In an effort to test my sbp_targ modifications, I fired up a FreeBSD 7 
initiator, and cvsup'd to RELENG_7. I then connected an external SBP2 
device that I got off of NewEgg. 

I was surprised to see it not work when I plugged it in:

This looks an awful lot like my issues with sbp_targ from previous 
emails and may indicate a more serious failure in fwohci.c or firewire.c

Or, it may indicate that I have no idea what I am doing.  :)

This SBP-2 device is a external 2 disk enclosure with an Oxford 
Semicondoctor F/W controller.  It seems to work just fine with linux and 
windows.
