bugfix: default floating border regression

Fixes a bug where a normal floating default border is not applied when
the default tiling border is set to a pixel value.

This bug was introduced in this commit:

43b447855d

Consider motif border for floating geometry

Fixes a comment that claimed default floating border could override
motif hints, which was never the case.

fixes #1305
