[PATCH V11 08/15] perf tools: remove references to struct ip_event

[Adrian Hunter <adrian.hunter@intel.com>]

struct ip_event assumes fixed positions for ip, pid
and tid.  That is no longer true with the addition of
PERF_SAMPLE_IDENTIFIER.  The information is anyway in
struct sample, so use that instead.
