[pve-devel] [PATCH qemu-server v2 10/15] api: {clone, move}_vm: use volume content type assertion helpers

[Daniel Kral <d.kral@proxmox.com>]

Make use of the newly introduced content type assertion helpers in the
preconditions check paths and the call to `vdisk_alloc` in the API
handlers for cloning VMs to another storage and moving a VM disk to
another storage with the newly introduced helper.

Since the preconditions existed before, adding a content type safeguard
at `vdisk_alloc` does not break the API.

changes since v1:
- split bug fix from refactoring (here)
- this was patch #3 and #4 before, but squashed them here as they are
  very related to each other
