Do not make it an error to call intel_edp_drrs_enable while drrs has
already been enabled, instead exit silently in this case.
This is a preparation patch for ensuring that DRRS is enabled on fastsets.
Note that the removed WARN_ON could also be triggered from userspace
through the i915_drrs_ctl debugfs entry which was added by
commit 35954e88bc50 ("drm/i915: Runtime disable for eDP DRRS")
