perf intel-pt: Fix "Unexpected indirect branch" error
commit 9fb523363f6e3984457fee95bb7019395384ffa7 upstream.
Some Atom CPUs can produce FUP packets that contain NLIP (next linear
instruction pointer) instead of CLIP (current linear instruction
pointer). That will result in "Unexpected indirect branch" errors. Fix
by comparing IP to NLIP in that case.
