In preparation for switching ITS allocations to the CoCo shared memory allocator, resolve the default node explicitly in its_alloc_pages_node(). The CoCo shared memory allocator interprets NUMA_NO_NODE as a request to apply the current task's memory policy. Resolving it to numa_mem_id() in the common ITS allocation helper preserves the existing nearest-memory-node placement for all callers This patch does not change the current allocation behavior.
