perf tools: Skip dynamic fields not defined for current event
When there are multiple events, each dynamic sort key is defined just
for one event. In this case other events will always show "N/A" for
those fields. But they are meaningless and consume precious screen
width.
Let's skip those undefined dynamic fields.
$ perf record -e kmem:kmalloc,kmem:kfree -a sleep 1
$ perf report -s 'comm,kmalloc.*' --stdio
# To display the perf.data header info, please use --header/--header-only options.
