[PATCH v2] drm/i915: Restore HDCP DRM_INFO when with no downstream

[Sean Paul]

The commit below returned earlier than before, but failed to move the
info message when authenticating without downstream devices. This patch
restores the message on authentication success.

Changes in v2:
- s/no downstream devices/no repeater present/ (Ram)
