net: remove unnecessary module_init/exit functions

Many network drivers have unnecessary empty module_init and module_exit
functions. Remove them (including some that just print a message). Note
that if a module_init function exists, a module_exit function must also
exist; otherwise, the module cannot be unloaded.
