Subject: perf help: Fix a bug during strstart() conversion
Git-commit: 2f0af8600e82e9f950fc32908386b9c639f88d48
Patch-mainline: v4.16-rc1
References: fate#325865,fate#325861
X-Info: duplicate(af98f2273fd0af31ce327cd1406b67c7be0b6734)

The commit 8e99b6d4533c changed prefixcmp() to strstart() but missed to
change the return value in some place.  It makes perf help print
annoying output even for sane config items like below:

$ perf help
  '.root': unsupported man viewer sub key.
  ...
