lvm secure erase bug with raw volume report from user forum

[DERUMIER, Alexandre]

Hi,

one user have reported a bug with secure erase on lvm raw

https://forum.proxmox.com/threads/erase-data-fills-ram.171556/

It's seem that the raw volumes are not forced to be activated before
erasing,so it's like we are writing to /dev/ , and fill the memory
instead erasing the volume.

I don't have verified it yet.

I'll look at it next week as I was also working on the patch to improve
speed.

(sorry to be late, I have super busy theses last weeks)
