dm log-writes: Add missing set_freezable() for freezable kthread
[ Upstream commit ab08f9c8b363297cafaf45475b08f78bf19b88ef ]
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.
Fixes: 0e9cebe72459 ("dm: add log writes target")
