kernel-shark: Make the "stop search" button always visible

So far the button was showing up only when we do a single-threaded
search in the data. Stopping the multi-threaded searches became
possible after the modification of the parallel search introduced
in the previous commit. When the multi-threaded search is restarted
(after being stopped) the label showing the number of matches found
is reset to show nothing. It will show the count again when the
search finishes or is stopped.
