[PATCH v2 04/14] perf mem: Only initialize memory event for recording

[Leo Yan]

It's needless to initialize memory events for perf reporting, so only
initialize memory event for perf recording.  This change allows to parse
perf data on cross platforms, e.g. perf tool can output reports even the
machine doesn't enable any memory events.
