module: remove meaningless 'name' parameter from __MODULE_INFO()
The symbol names in the .modinfo section are never used and already
randomized by the __UNIQUE_ID() macro.
Therefore, the second parameter of __MODULE_INFO() is meaningless
and can be removed to simplify the code.
With this change, the symbol names in the .modinfo section will be
prefixed with __UNIQUE_ID_modinfo, making it clearer that they
originate from MODULE_INFO().
