interconnect: qcom: osm-l3: fix icc_onecell_data allocation 

[ Upstream commit f77ebdda0e ]

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.

Fixes: 5bc9900add ("interconnect: qcom: Add OSM L3 interconnect provider support")
