[DRBD-user] linstor-proxmox: Intentionally removing diskless assignment

[Andreas Pflug]

The NOTICE "Intentionally removing diskless assignment (vm-nnn-disk-n)
on (nodeX)" is printed whenever a VM is migrated away from a diskless
node (PVE6.1). This is no error and just the way the plugin is supposed
to work, still it is printed as "Error: migration problems" marked red
and thus alarming.
I'd rather love to see the plugin quiet on this occasion.

Regards,
Andreas
