MINOR: pattern: fix pat_{parse,match}_ip() function comments

Function comments were outdated, probably because they have not been
updated during the previous refactors.

Fixing comments to better reflect the current behavior.

This may be backported up to 2.2, or even 2.0 by slightly adapting the
patch (in 2.0, such functions are documented in proto/pattern.h)
