When module is not present and the open coded patient module
remover is called we'll end up in a loop which never ends.
Fix this.

I actually found this issue not in fstests, but when applying this
open coded solution to blktests. In fstest we tend to only call
module remove when we have a module loaded. blktests is different,
and so I immediately spotted the issue there.
