mei: hdcp: fix mei_hdcp_verify_mprime() input parameter
wired_cmd_repeater_auth_stream_req_in has a variable length array at the end. we use struct_size() overflow macro to determine the size for the allocation and sending size. This also fixes bug in case number of streams is > 0 in the original submission. This bug was not triggered as the number of streams is always one.
