dm log-writes: Add missing set_freezable() for freezable kthread 



The log_writes_kthread() calls try_to_freeze() but lacks set_freezable(),
rendering the freeze attempt ineffective since kernel threads are
non-freezable by default. This prevents proper thread suspension during
system suspend/hibernate.

Add set_freezable() to explicitly mark the thread as freezable.
