Subject: cli: Fix pool=default when path belongs to another pool (bz 1692489)

Using 'virt-install --disk size=X' implicitly uses pool=default. If
a pool named 'default' exists we use that; if not, and a pool using
the default path exists under a different name, we attempt to use
that as well, and if that doesn't exist, we create pool=default

The second case is broken, so if there's no pool=default and eg.
pool=FOO points to /var/lib/libvirt/images, we still attempt to
look up pool=default which understandably fails
