lightnvm: disable the subsystem

stable inclusion
from stable-v5.10.114
commit 549209caabc89f2877ad5f62d11fca5c052e0e8f
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5O6A9
CVE: CVE-2022-2991

---------------------------

In commit 9ea9b9c4 ("remove the lightnvm subsystem") the lightnvm
subsystem was removed as there is no hardware in the wild for it, and
the code is known to have problems.  This should also be disabled for
older LTS kernels as well to prevent anyone from accidentally using it.
