Michael Lass ff85c82151 dims_create: fix calculation of factors for odd squares ...

Until now sqrt(n) was missed as a factor for odd square numbers n. This
lead to suboptimal results of MPI_Dims_create for input numbers like 9,
25, 49, ... Fix the results by including sqrt(n) in the search for
factors.
