metropolis: fix handling GPT holes

GPT tables can have "holes" i.e. unused partition slots. These are
represented as nil values. Code walking these tables did not consider
that partition entries might be nil.
Fix the call sites and improve the gpt package documentation to
explicitly mention the need to check IsUnused.
