net: marvell: prestera: fix incorrect structure access

CVE-2021-47102

Description

In the Linux kernel, the following vulnerability has been resolved:

In line: upper = info->upper_dev; We access upper_dev field, which is related only for particular events (e.g. event == NETDEV_CHANGEUPPER). So, this line cause invalid memory access for another events, when ptr is not netdev_notifier_changeupper_info.

The KASAN logs are as follows:
