perf kmem: Show warning when trying to run stat without record
Sometimes one can mistakenly run 'perf kmem stat' without running 'perf
kmem record' before or with a different configuration like recording
--slab and stat --page. Show a warning message like the one below to
inform the user:
# perf kmem stat --page --caller
No page allocation events found. Have you run 'perf kmem record --page'?
