misc/mei/hdcp: Fix AUTH_STREAM_REQ cmd buffer len
Fix the size of WIRED_REPEATER_AUTH_STREAM_REQ cmd buffer size.
It is based upon the actual number of MST streams and size
of wired_cmd_repeater_auth_stream_req_in.
Excluding the size of hdcp_cmd_header.
v2:
- hdcp_cmd_header size annotation nitpick. [Tomas]
