block: move bdev_mark_dead out of disk_check_media_change
disk_check_media_change is mostly called from ->open where it makes little sense to mark the file system on the device as dead, as we are just opening it. So instead of calling bdev_mark_dead from disk_check_media_change move it into the few callers that are not in an open instance. This avoid calling into bdev_mark_dead and thus taking s_umount with open_mutex held.
