[PATCH AUTOSEL 4.4 1/5] module: set MODULE_STATE_GOING state when a module fails to load

[Sasha Levin]

From: Miroslav Benes <mbenes@xxxxxxx>

[ Upstream commit 5e8ed280dab9eeabc1ba0b2db5dbe9fe6debb6b5 ]

If a module fails to load due to an error in prepare_coming_module(),
the following error handling in load_module() runs with
MODULE_STATE_COMING in module's state. Fix it by correctly setting
MODULE_STATE_GOING under "bug_cleanup" label.
