  [flang][cuda] Fix invalid host free of managed allocatable function results (#209945)

An allocatable function result with a CUDA data attribute is allocated
with the CUDA allocator, but the caller freed the temporary with a host
`free` (via `hlfir.destroy` → `fir.freemem`), corrupting the heap.
Release it through the CUDA-aware deallocation (`cuf.deallocate`)
instead.
