Subject: [PATCH] perf/x86: Suppress duplicated abort LBR records

Haswell always give an extra LBR record after every TSX abort.
Suppress the extra record.

This only works when the abort is visible in the LBR
If the original abort has already left the 16 LBR entries
the extra entry will will stay.
