Tomas Winkler 51072c0f5b 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.
