Restore a CUDA device pointer previously acquired with VecCUDAGetArrayRead().
PETSC_EXTERN PetscErrorCode VecCUDARestoreArrayRead(Vec v, const PetscScalar **a)
If the data on the host side was previously up to date it will remain
so, i.e. data on both the device and the host is up to date.
Accessing data on the host side e.g. with VecGetArray() does not
incur a device to host data transfer.
This function is not currently available from Fortran.
