x86/oprofile: Rework and simplify nmi_cpu_setup()
This patch removes the function nmi_save_registers(). Per-cpu code is now executed only in the function nmi_cpu_setup(). Also, it renames the per-cpu function nmi_restore_registers() to nmi_cpu_restore_registers(). Signed-off-by: Robert Richter <robert.richter@amd.com>
