tests/kms_setmode: avoid 2 connectors on the same encoder
Don't try to set modes on two connectors that share the same encoder. That will just fail. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=68463 Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com>
