[pve-devel] [PATCH guest-common] replication: avoid "expected snapshot missing warning" when irrelevant

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

Namely, when there are no snapshots at all on the volume, which also
is the case when the volume doesn't exist. This happens when a fresh
volume is added to an already replicated guest.

Fixes replication tests in pve-manager, which didn't like the additional
output.

Fixes: c0b2948 ("replication: prepare: safeguard against removal if expected snapshot is missing")
