    interconnect: qcom: osm-l3: fix icc_onecell_data allocation
    
    [ Upstream commit f77ebdda0ee652124061c2ac42399bb6c367e729 ]
    
    This is a struct with a trailing zero-length array of icc_node pointers
    but it's allocated as if it were a single array of icc_nodes instead.
    
    Fortunately this overallocates memory rather then allocating less memory
    than required.
    
    Fix by replacing devm_kcalloc() with devm_kzalloc() and struct_size()
    macro.
