ia64: revert __node_random addition
This partially reverts commit 4ec37de89d8c758ee8115e0e64b3f994910789ee ("[IA64] Fix build breakage"), since the commit that made it necessary got reverted earlier (see commit 35926ff5fba8, 'Revert "cpusets: randomize node rotor used in cpuset_mem_spread_node()"') Even if we ever re-introduce this, there is no reason to make __node_random be some architecture-specific function.
