[PATCH] mke2fs: fix up topo complaints on regular files

[Eric Sandeen <sandeen@redhat.com>]

mkfsing a plain file would lead to a warning about being unable
to determine geometry; we should just skip the topology-getting
if we see that we have a regular file.

This was breaking "make check" but I had missed it since I
inadvertently stopped running the checks during the Fedora
RPM build.

Also, add a newline to the warning.
