/**
Testcase Scenarios :
Negative -
1) Pass node as nullptr and verify api returns error code.
2) Pass un-initialize node and verify api returns error code.
3) Pass pNodeParams as nullptr and verify api returns error code.
Functional -
1) Create a graph, add Memcpy node to graph with desired node params.
   Verify api fetches the node params mentioned while adding Memcpy node.
2) Set Memcpy node params with hipGraphMemcpyNodeSetParams,
   now get the params and verify both are same.
