[pbs-devel] [PATCH proxmox-backup] ui: tape: fix restore datastore mapping parameter construction

[Dominik Csapak <d.csapak@proxmox.com>]

We recently took into account the selected datastore when restoring from
tape, but the snapshot grids value may not only be a single datastore, it can
also be a list of snapshots, datastores or 'all'.

handle these cases and extract the source datastore correctly.

This fixes tape restoration when not a whole datastore is selected.

this patch should also apply cleanly on the stable-2 branch currently
