rS327346: Fix potential TOCTTOU bug in the geli tests

Summary

Fix potential TOCTTOU bug in the geli tests

This change mostly reverts r293436, which introduced the bug due to a belief
that geli(8) would allocate md(4) devices by itself. However, that belief is
incorrect. Instead of using linear probing to find available md(4) numbers,
it's best to use the existing attach_md function.
