Fix restoring a backup volume to a larger volume

We cannot restore a backup to a larger volume on ceph because it
fails with status "error_restoring". This patch adds read/write
permissions to volumes pool for backup user. We need such permissions
to change volume size during restoring backup when the backup is
smaller than a volume.
