Subject: [PATCH] perf tools: Fixup for removing -f option in perf record

From: Namhyung Kim <namhyung.kim@....com>

The commit bf3da4014a0c ("perf record: Remove -f/--force option") got
rid of -f option from perf record.  But this option was used
internally by various sub-commands so they wouldn't work anymore.
Also update the example document not to use -f option.
