Subject: [PATCH 1/2] crypto: qat: replace get_current_node() with numa_node_id()

From: Andre Przywara <[email protected]>

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.
