commit d3dc04cd81e0eaf50b2d09ab051a13300e587439 upstream.
This reverts commit 15b2219facadec583c24523eed40fa45865f859f.
Before IO threads accepted signals, the freezer using take signals to wake up an IO thread would cause them to loop without any way to clear the pending signal. That is no longer the case, so stop special casing PF_IO_WORKER in the freezer.
