vol restore discard leaves final bytes unzeroed

[Edward Hope-Morley]

When doing a volume restore with Ceph backend to a non-rbd volume that is greater in size that the backup volume, we write zeroes the extraneous extents but we are not zeroing the final few bytes.

This should have gone into 1225126 but I did not catch it until after it was merged.

    Fixes vol restore discard final bytes unzeroed

    When doing a volume restore with Ceph backend to a non-rbd volume
    that is greater in size that the backup volume, we write zeroes
    the extraneous extents but we are not zeroing the final few bytes
    in the case where the destination volume is non-rbd.

    Also fixed up internationalisation on a number of log messages.
