Report error if dimensions of chunked storage in data layout < 2 (#2241)
For Data Layout Messages version 1 & 2 the specification state
that the value stored in the data field is 1 greater than the
number of dimensions in the dataspace. For version 3 this is
not explicitly stated but the implementation suggests it to be
the case.
Thus the set value needs to be at least 2. For dimensionality
< 2 an out-of-bounds access occurs as in CVE-2021-45833.
This fixes CVE-2021-45833 / Bug #2240.
