MFC r324445:
When showing the sleepqueues from the in-kernel debugger,
properly dump all the sleepqueues and not just the first one

History:
It appears that in the commit which introduced the code,
r165272, the array indexes of "sq_blocked[0]" and "td_name[i]"
were interchanged. In r180927 "td_name[i]" was corrected to
"td_name[0]", but "sq_blocked[0]" was left unchanged.
