[PATCH proxmox-backup 07/10] chunk_store: check file system space before inserting new chunks

[Robert Obkircher <r.obkircher@proxmox.com>]

This is done here to cover all possible paths (including tape restore)
and to avoid the check for exiting chunks.

Note that the atime update check invoked by gc and prune jobs tries to
insert a zero chunk. However, that chunk is already inserted during
datastore creation and never removed, so this should not prevent them
from running on a full disk.
