Subject: net: kABI workaround for ax25_dev
Patch-mainline: Never, kABI workaround
References: CVE-2022-1199 bsc#1198028

The recent fix for ax25 added a new field to ax25_dev struct.
Let's hide it with the standard __GENKSYMS__ trick for kABI
compatibility, as the struct is kmalloced internally in ax25 core
itself.
