The vtn_ssa_value for a cmat is not backed by a nir_def, but by a nir_variable, so
can't be used directly when calling a function. In most cases the cmat is used by
reference so code will take the value of deref for it (which is a `nir_def`).
When passing a cooperative matrix to a function by value, let the caller pass the deref
value, and the callee copy to a new local variable from that deref.
