perf intel-pt: decoder: Factor out clearing of FUP (Flow Update) event variables
Factor out clearing of FUP (Flow Update) event variables, to avoid code duplication.
Committer Notes:
From the Intel documentation:
<quote>
Flow Update Packets (FUP): FUPs provide the source IP addresses for
asynchronous events (interrupt and exceptions), as well as other cases
where the source address cannot be determined from the binary.
