LOG: [mlir] NFC - Drop spurious assertion on symbols during `promoteComposedSymbolsAsDims`

This assertion is an old remnant from earlier days when only affine functions existed.
It is not the place of affine map composition to check whether orthogonal considerations
on what is allowed to be a symbol under the AffineScope trait.
