[PATCH 6.18 211/752] jfs: Add missing set_freezable() for freezable kthread

[ Upstream commit eb0cfcf265714b419cc3549895a00632e76732ae ]

The jfsIOWait() thread calls try_to_freeze() but lacks set_freezable(),
causing it to remain non-freezable by default. This prevents proper
freezing during system suspend.

Add set_freezable() to make the thread freezable as intended.
