  [MLIR] Add missing check for unsupported affine dependence analysis

Add missing check in affine dependence analysis when dependence analysis
isn't possible due to the ops being in different affine scopes.  The
lack of such a check could lead to a crash or incorrect behavior in
several dependent utilities.
