[PATCH i-g-t 4/4] tests/kms_content_protection: Make mst_cp_enable_with_retry() void

[Suraj Kandpal <suraj.kandpal@intel.com>]

Change the return type for test_mst_cp_enable_with_retry to void
since it really does not need to return anything back now that
the color change and enablement verification happen inside the
function itself.
