[pve-devel] [PATCH installer] sys: block: fix inverted check when detecting block size

[Christoph Heiss]

We do actually want the block size if it is integer - currently, it is
always set to `undef` (and then `null` in the serialized JSON).

Fixes: 15b2cd7 ("sys: block: fix possible use of `undef`-value when detecting disk sizes")
