canCFunEqCan: use isTcReflexiveCo (not isTcReflCo)
As Trac #15577 showed, it was possible for a /homo-kinded/
constraint to trigger the /hetero-kinded/ branch of canCFunEqCan,
and that triggered an infinite loop.
The fix is easier, but there remains a deeper questions: why is
the flattener producing giant refexive coercions?
