rocprofler_iterate_info workaround v2 (#271)

Revert agent_info->dev_index in hsa_rsrc_factory.cpp

- disable using the driver_node_id and, instead, start at zero
  because it breaks the lookup for rocprofiler_pool_fetch
  lookup in rocprofiler.cpp. On my system (one AMD GPU and
  one NVIDIA GPU), it has a value of 1, not 0 and the pool
  size is 1 -- resulting in segfault
