[PATCH 2/2] perf, x86: Don't mark DataLA addresses as store

[Andi Kleen]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Haswell supports reporting the data address for a range
of events, including UOPS_RETIRED.ALL and some load
events. Currently these addresses were always marked
as stores, which is wrong, as they could be loads too.
Change it to NA instead.
