perf intel-pt: Clear FUP flag on error
commit 6a558f12dbe85437acbdec5e149ea07b5554eced upstream.
Sometimes a FUP packet is associated with a TSX transaction and a flag is
set to indicate that. Ensure that flag is cleared on any error condition
because at that point the decoder can no longer assume it is correct.
