[pve-devel] [PATCH storage] fix 3214: storage dir structure creation with mkdir 0

[Aaron Lauterer <a.lauterer@proxmox.com>]

We fail early when `mkdir 0` is set for the storage to avoid creating
the directories in the storage path.

This means that once `mkdir 0` is set, the code to create the needed
directory structure (e.g. dump, image, ...) at the storage location will
never run.

Adding an additional check to only return early if the storage path
currently does not exist solves the problem.
