[PATCH i-g-t v1] igt_kms: Allow pipes with no cursor plane

[PATCH i-g-t v1] igt_kms: Allow pipes with no cursor plane

[Robert Foss]

A cursor plane may not always be available. Since there
already exist variables that signal the existance or
non-existance of cursor planes like pipe->plane_cursor and
display->has_cursor_plane, allow the pipes that have no
cursor plane.
