[PATCH 2/3] modules: set mod->state to GOING before going notifiers are called

[Jessica Yu]

In load_module(), the going notifiers are called during error handling
when an error occurs after the coming notifiers have already been called.
However, a module's state is still MODULE_STATE_COMING when the going
notifiers are called in the error path. To be consistent, also set
mod->state to MODULE_STATE_GOING before calling the going notifiers.
