PM / Hibernate: When failed, in_suspend should be reset
When hibernation failed due to an error in swsusp_write() called by hibernate(), it skips calling "power_down()" and returns. When hibernate() is called again (probably after fixing up so that swsusp_write() wouldn't fail again), before "in_suspend = 1" of create_image is called, in_suspend should be 0. However, because hibernate() did not reset "in_suspend" after a failure, it's already 1. This patch fixes such inconsistency of "in_suspend" value.
