nilfs2: add missing set_freezable() for freezable kthread

Browse Source 
The kernel thread function nilfs_segctor_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.
