perf report: Fix incorrectly added dimensions as switch perf data file
We observed an issue that was some extra columns displayed after switching
perf data file in browser. The steps to reproduce:
1. perf record -a -e cycles,instructions -- sleep 3
2. perf report --group
3. In browser, we use hotkey 's' to switch to another perf.data
4. Now in browser, the extra columns 'Self' and 'Children' are displayed.
The issue is setup_sorting() executed again after repeat path, so dimensions
are added again.
This patch checks the last key returned from __cmd_report(). If it's
K_SWITCH_INPUT_DATA, skips the setup_sorting().
Fixes: ad0de0971b7f ("perf report: Enable the runtime switching of perf data file")
