[RFC 2/2] perf: duct tape a crash on perf kvm --guestmount=$(pwd) report

[Sebastian Andrzej Siewior]

Data was collected with
|perf kvm --guestmount=$(pwd) record -a -R -g -s -d -T

After executing
|kvm --guestmount=$(pwd) report

I ended up with two segfaults. This patch duct tapes both of them.
Most likely there is some infomration missing.
