In preparation for switching ITS allocations to the CoCo shared memory allocator, resolve the default node explicitly in its_alloc_pages(). The CoCo shared memory allocator interprets NUMA_NO_NODE as a request to apply the current task's memory policy. Passing numa_mem_id() instead preserves the existing nearest-memory-node placement across the allocator switch. This patch does not change the current allocation behavior.
