 Fix an outright bug in the unflattener

 Trac #14554 showed up an outright bug in the unflattening code in
 TcFlatten.  I was filling in a coercion with the wrong coercion (a Syn
 in the wrong place).  Result: "Bad coercion hole" assertion failures,
 and Core Lint Errors.

 Easily fixed, and the code is simpler too.
