gelu layer setName using util::node_info(n).c_str()

[itsliupeng]

Description

Set name of Gelu layer to "util::node_info(n).c_str()" instead of string "gelu", to prevent "Repeated layer name: gelu (layers must have distinct names)" error when building tensorrt engine from a module with multiple gelu layers.

Also format "trtorch::core::util::node_info(n).c_str()" to "util::node_info(n).c_str()".
