There have been reports about user swap memory being a value that looks like an overflow. At the moment used swap memory is calculated as the value of total memory minus the free memory, so this means that free memory is bigger than total in some cases. This isn't possible in principle. Assume that no swap is being used if that happens. (cherry picked from commit 7d9b2e3)

Cherry-pick of PR #9383 to 6.x branch. Original message:
There have been reports about user swap memory being a value that looks
like an overflow. At the moment used swap memory is calculated as the
value of total memory minus the free memory, so this means that free
memory is bigger than total in some cases. This isn't possible in
principle. Assume that no swap is being used if that happens.
Closes #6271
