[libvirt] [PATCH] docs: Point to list of valid pool target volume formats

[John Ferlan]

https://bugzilla.redhat.com/show_bug.cgi?id=1092886

Rather than point off to some nefarious "pool-specific docs" page when
describing the "format" field for the target pool provide a link to the
storage driver page which describes the various valid formats for each
pool type.  Also make it a bit more clear that if a valid format isn't
specified, then the type field is ignored.
