[virt-tools-list] [PATCH virt-manager] details: fix --show-domain-performance

[Giuseppe Scrivano]

the introspection page could be missing, in this case the tabs values
are shifted by one.  The new code looks for the correct row number
before selecting it.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1167600
