[pve-devel] [PATCH container v2] lxc: resize: fix #2790 return message in case of disk already at size

Otherwise the API would return an error message because returning an
empty value is not defined in the API.

By dying we avoid confusions as the return will be an error and not a
successful call which should return a task ID.

v1 -> v2: change from return to die as the result of the feedback to the
first version [0]

We should probably align the resize endpoint on the qemu side
accordingly as right now it has no return values defined at all and does
not return anything in this case.
