tracing/ring-buffer: don't annotate rb_cpu_notify with __cpuinit

Impact: remove a section warning

CONFIG_DEBUG_SECTION_MISMATCH raises the following warning on -tip:

  WARNING: kernel/trace/built-in.o(.text+0x5bc5): Section mismatch in
  reference from the function ring_buffer_alloc() to the function
  .cpuinit.text:rb_cpu_notify()
  The function ring_buffer_alloc() references
  the function __cpuinit rb_cpu_notify().

This is actually harmless. The code in the ring buffer don't build
rb_cpu_notify and other cpu hotplug stuffs when !CONFIG_HOTPLUG_CPU
so we have no risk to reference freed memory here (it would even
be harmless if we unconditionally build it because register_cpu_notifier
would do nothing when !CONFIG_HOTPLUG_CPU.

But since ring_buffer_alloc() can be called everytime, we don't want it
to be annotated with __cpuinit so we drop the __cpuinit from
rb_cpu_notify.

This is not a waste of memory because it is only defined and used on
CONFIG_HOTPLUG_CPU.
