Fix the bug where the thread worker constantly looped. It was a race as
to whether or not the thread fired up or a polled/probed command happened
first, or maybe it's due to other scsipi changes, but we never set the
value that caused the fc thread worker to actually go to sleep until an
initial loop up.

This was rather ugly as it consumed nearly all CPU time available from thence
on. Bad.
