drm/i915/hdcp: Fix config_stream_type() ret value
DP shim's config_stream_type considered to be succeeded when
return value of intel_dp_hdcp2_write_msg() equals to size of
message to be written, it makes config_stream_type to return
a zero success value in order to succeed the HDCP auth.
v2:
- config_stream_type() returns 0 on success. [Ram]
