perf annotate: Prefer cmdline option over default config 

For all the perf-config options that can also be set from command line
option, the preference is given to command line version in case of any
conflict. But that's opposite in case of perf annotate. i.e. the more
preference is given to default option rather than command line option.
Fix it.

Before:

  $ ./perf config
  annotate.show_nr_samples=false

  $ ./perf annotate shash --show-nr-samples
