    Fix listen server sending snapshots each client frame
    
    Running a server using the client engine would send server snapshots
    to loopback and LAN clients each client frame (com_maxfps).
    
    This causes excessive network traffic and likely does not provide new
    information to the clients because SV_Frame() won't have run between
    the extra snapshots.
    
    This commit restores the original behavior of respecting local/LAN
    client's snaps userinfo and sv_fps. The issue was introduced by the
    following commit:
