If the PTE page table lock is acquired by pte_offset_map_lock(), the lock must be released via pte_unmap_unlock(). However, in damos_va_migrate_pmd_entry(), if damos_va_filter_out() returns true, it immediately returns without releasing the lock. This fixes the issue by not stopping page table traversal when damos_va_filter_out() returns true and ensuring that the lock is released.
