[pbs-devel] [PATCH proxmox-backup] api: list-snapshots improvements

[Gabriel Goller]

`full_path` did not use the cached time string. By using it we avoid a
call to the super-slow libc strftime.

Fix a comment typo.

`list_snapshots_blocking` doesn't need to be unsafe.

The `protected` attribute of a backup has already been checked, avoid
retrieving it another time.
