      Impact: fix to prevent developers from using entry->cpu
      With the new ring buffer infrastructure, the cpu for the entry is
      implicit with which CPU buffer it is on.
      The original code use to record the current cpu into the generic
      entry header, which can be retrieved by entry->cpu. When the
      ring buffer was introduced, the users were convert to use the
      the cpu number of which cpu ring buffer was in use (this was passed
      to the tracers by the iterator: iter->cpu).
      Unfortunately, the cpu item in the entry structure was never removed.
      This allowed for developers to use it instead of the proper iter->cpu,
      unknowingly, using an uninitialized variable. This was not the fault
      of the developers, since it would seem like the logical place to
      retrieve the cpu identifier.
      This patch removes the cpu item from the entry structure and fixes
      all the users that should have been using iter->cpu.
