`$size` and `$logical_bsize` might get unset if there invalid, but then
are unconditionally converted to an int - which throws an error.
This was reported on the forum by a user [0].

Fix it by changing the check a bit to skip the disk immediately if
detecting either of those two values are invalid or simply not present.
The fix for `$logical_bsize` simply avoids trying to convert to value to
an int if invalid.

tl;dr: Should have no impact at all, in the end. The same
`run-env-info.json` is generated w/ and w/o the patch if all disks are
fine. I then also hacked up the script a bit to actually have an invalid
size, this resulted in the "affected" disk simply missing from the disk
array - the expected behavior in this case.
