perf intel-pt: decoder: Factor out clearing of FUP (Flow Update) event variables

Browse source 
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.
