[Ovirt-devel] [PATCH node] Removes a confusing storage message.

[Darryl L. Pierce]

If interactively configuring storage, the user is shown this message
when configuration the data partition:

Change data partition size. (Current -1 MB, Minimum 5 MB)

This is confusing to read, and is misleading since the data partition
size can be 0, indicating the user does not want a data partition.

So the minimum size is set to 0. When the prompt is show, only those
partitions that have a non-zero minimum size are displayed with such a
message.
