Remove "unsafe" from module struct
Adrian Bunk points out that "unsafe" was used to mark modules touched by the deprecated MOD_INC_USE_COUNT interface, which has long gone. It's time to remove the member from the module structure, as well. If you want a module which can't unload, don't register an exit function. (Vlad Yasevich says SCTP is now safe to unload, so just remove the __unsafe there).
