Matt Jacob e95725cb76 Most of these changes to isp are to allow for isp.ko unloading. 
We also revive loop down freezes. We also externaliz within isp
isp_prt_endcmd so something outside the core module can print
something about a command completing. Also some work in progress to
assist in handling timed out commands better.
