perf callchain: Fixup parameter handling error message
Fix up parse_callchain_record_opt error message for 'fp', in the past using '-g
fp' was a valid alternative to '--call-graph fp', which is not the case since:
commit 09b0fd45ff63413df94cbd832a765076b201edbb
Author: Jiri Olsa <jolsa@redhat.com>

perf record: Split -g and --call-graph
I.e. -g means "use the configured unwind data collection method" which has as
default 'fp', while --call-graph requires passing the method to use.
