[pve-devel] [PATCH stable-7 guest-common] storage tunnel: correctly set disk-import parameters

[Fiona Ebner <f.ebner@proxmox.com>]

From: Fabian Grünbichler <f.gruenbichler@proxmox.com>

according to the schema, else some combinations of migration / guest /
storage settings will fail validation:

2024-05-15 11:48:51 ERROR: migration_snapshot: type check ('boolean') failed - got ''

since this is client / source side, remote migrations to a remote node
with validation enabled can fail without this change.

The fact that this is required for Proxmox VE 7 was reported in the
community forum:
https://forum.proxmox.com/threads/158202/

While Proxmox VE 7 is end-of-life since the end of July 2024, it's
still nice to keep upgrade paths to supported versions open.
