tests/kms_plane_scaling: Fix off-by-one plane selection
Commit ca20170afc6f ("tests/kms_plane_scaling: Add support for dynamic
number of planes") shifted the tested planes by one after the
refactoring, accidentally ignoring the first plane, which is zero
indexed. A symptom of the issue appears on KBL, where the third plane
is already the shared cursor, causing igt to configure an unsupported
framebuffer format on it, triggering the following error:
[drm:__setplane_internal] Invalid pixel format XR24 little-endian (0x34325258)
With this fixed, we can exposes the pixel clock scaling issue, which is
the actual problem being tracked in Bug 103159, but let's start by
reverting to the old behavior.
