Fix api error message for snapshot creation failure

when the source share has ``snapshot_support`` False.

The message said that the back end lacks snapshot support but this
is not necessarily the case.

Corrected an error message for attempts to create snapshots from shares
that do not support this operation. The message said that the share
backend has no such support but that is not always true. The original
share for the snapshot does not support snapshots because it was created
with a share type without the ``snapshot_support`` extra-spec set,
irrespective of whether the back end used can itself support snapshots
or not.
