[virt-tools-list] [PATCH virt-viewer 4/4] virt-viewer-main: '--wait' should not be used without domain name

[Pavel Grunt]

Commit a830275344c88aef12166661b68ea2b4429c7212 required the domain
name to be placed just after the '--wait' option. It breaked the
command line api, because running 'virt-viewer $vm --wait' was considered
as the error.

This patch rather checks whether the domain name was specified.
