[libvirt] [RFC 3/7] tools: Print warnings in virsh

[Andrea Bolognani]

We delay dealing with actual errors until a later, more
appropriate time in general, but if we wanted to do the same
with warnings we'd have to introduce a lot of duplicated
handling in virsh, so we just print them right away and move
on with the usual processing instead.
