[mlir][linalg] Fix neutral elt for softmax (#118952)
The decomposition of `linalg.softmax` uses `maxnumf`, but the identity
element that is used in the generated code is the one for `maximumf`.
They are not the same, as the identity for `maxnumf` is `NaN`, while the
one of `maximumf` is `-Infty`. This is wrong and prevents the maxnumf
from being folded.

Related to #114595, which fixed the folder for maxnumf.
