[PATCH - storage] simple fixes for storage rewrite

[Chris Lumens <clumens redhat com>]

I've been working on merging booty back into anaconda and adapting it to use
the new storage code.  While doing that, I've run into a variety of small,
obvious bugs.  I don't think anyone else has seen these yet since they're all
after the bootloader screens in anaconda, which is where everyone's currently
getting hung up.

These should all be merged into the storage branch now.  I don't think they
require the new booty code at all.

Once I have an install that completes (which should be fairly soon - it's
installing packages right now) then I will post my booty patches.  Those
are also against the storage branch.
