ANDROID: AVB error handler to invalidate vbmeta partition. If androidboot.vbmeta.invalidate_on_error is 'yes' and androidboot.vbmeta.device is set and points to a device with vbmeta magic, this header will be overwritten upon an irrecoverable dm-verity error. The side-effect of this is that the slot will fail to verify on next reboot, effectively triggering the boot loader to fallback to another slot. This work both if the vbmeta struct is at the start of a partition or if there's an AVB footer at the end. This code is based on drivers/md/dm-verity-chromeos.c from ChromiumOS.
