Adrian Hunter 25e902d666 perf intel-pt: Fix TSC slip 
commit f3b4e06b3b upstream.

A TSC packet can slip past MTC packets so that the timestamp appears to
go backwards. One estimate is that can be up to about 40 CPU cycles,
which is certainly less than 0x1000 TSC ticks, but accept slippage an
order of magnitude more to be on the safe side.
