drm/i915/hdcp: No HDCP when encoder is't initialized

Browse source

There can be situation when DP MST connector is created without
mst modeset being done, in those cases connector->encoder will be
NULL. MST connector->encoder initializes after modeset.
Don't enable HDCP in such cases to prevent any crash.
