[pbs-devel] [PATCH proxmox-backup] notification: don't deserialize notification config when there is nothing to send

[Lukas Wagner]

The privileged daemon checks every couple seconds if the unprivileged
daemon has enqueued any notifications. This change makes the worker
function exit early if there is no notification to send, which allows us
to avoid deserializing the notification config when it is not really
needed.

Notes:
    Noticed this by accident when using `strace` to debug some other issue
    reported in the forum.
