port-share: log incoming connections at verb 3 only

port-share: log incoming connections at verb 3 only

From "day 1" the message "Non-OpenVPN client protocol detected" was
logged at D_STREAM_ERRORS level (verb 1), while it is not anything
erroneous in this context (it's inside an "port share" only block).

Bump this to D_PS_PROXY (verb 3).
