[pbs-devel] [PATCH proxmox-backup] fix #4357: datastore: take into account namespaces when marking chunks

[Stefan Sterz <s.sterz@proxmox.com>]

previously when marking used chunks the namespace wasn't taken into
account and valid snapshots were marked as "strange paths". this lead
to a line in the log of a gc job such as this:

found (and marked) 2 index files outside of expected directory scheme

which some users perceived as an error. parse the namespace too and
only mark the path as strange if parsing the namespace and/or backup
dir fails.
