     ("dm thin: return -ENOSPC when erroring retry list due
    to out of data space") was a step in the right direction but didn't go
    far enough.
    Add a new 'out_of_data_space' flag to 'struct pool' and set it if/when
    the pool runs of of data space.  This fixes cell_error() and
    error_retry_list() to not blindly return -EIO.
    We cannot rely on the 'error_if_no_space' feature flag since it is
    transient (in that it can be reset once space is added, plus it only
    controls whether errors are issued, it doesn't reflect whether the
    pool is actually out of space).
