[pbs-devel] [PATCH v5 proxmox-backup 04/31] config: acl: refactor acl path component check for datastore

[Christian Ebner]

Combine the two if statements checking the datastores ACL path
components, which can be represented more concisely as one.

Further, extend the pre-existing comment to clarify that `datastore`
ACL paths are not limited to the datastore name, but might have
further sub-components specifying the namespace.
