[virt-tools-list] [PATCH 1/2] Simplify virt_viewer_auth_libvirt_credentials() return value logic

[Fabiano Fidêncio]

As the function should return < 0 in error cases, let's explicitly
return/set the return value to -1 in error cases. Otherwise, the
function will return 0.

This patch also fixes a regression introduced by (a5ce2ed3).
