perf tools: Remove misleading comments on map functions

When it converts sample IP to or from objdump-capable one, there's a comment saying that kernel modules have DSO_SPACE__USER. But commit 02213ce ("perf maps: Mark module DSOs with kernel type") changed it and makes the comment confusing. Let's get rid of it.
