[ Upstream commit c2a1b91e47984e477298912ffd55570095d67318 ]
Currently the QAT driver code uses a self-defined wrapper function called get_current_node() when it wants to learn the current NUMA node. This implementation references the topology_physical_package_id[] array, which more or less coincidentally contains the NUMA node id, at least on x86.
Because this is not universal, and Linux offers a direct function to learn the NUMA node ID, replace that function with a call to numa_node_id(), which would work everywhere.
This fixes the QAT driver operation on arm64 machines.
