[Crash-utility] [PATCH] Fix "kmem -v" option on Linux 5.11-rc1 and later kernels

[HAGIO KAZUHITO(萩尾 一仁)]

Fix the "kmem -v" option on Linux 5.11-rc1 and later kernels
that contains commit 96e2db456135db0cf2476b6890f1e8b2fdcf21eb
("mm/vmalloc: rework the drain logic").  Without the patch,
the option will display nothing or fail with the error message
"kmem: invalid kernel virtual address: <address>  type: "vmlist addr".
