Subject: [PATCH 2/4] kernel-shark: Allow unsetting of all CPUs in filter

From: Vaibhav Nagarnaik <vnagarnaik@...gle.com>

The button "All CPUs" in CPU filter dialog allows setting of all CPUs
but doesn't clear CPUs when it is unchecked. Make sure that when the
"All CPUs" button is unchecked, all the CPUs get unchecked.

Tested: In kernelshark, go to Filter->list CPUs and uncheck "All CPUs"
button. All the CPUs should be unchecked at that point.
