powerpc/ps3: Add missing set_freezable() for ps3_probe_thread()

Browse Source 
The kernel thread function ps3_probe_thread() invokes the try_to_freeze()
in its loop. But all the kernel threads are non-freezable by default.
So if we want to make a kernel thread to be freezable, we have to invoke
set_freezable() explicitly.
