The intention is that you should be able to use quota(2) to switch from one
quota file to another, without losing any data, though exactly why I thought
this would be a useful thing to do is a mystery to me now.

Re-enabling the same quota file should be a harmless no-op.

The kernel is supposed to hadle it (the test is the first executable line
in opendq() in quota_kern.c), though I must admit to not having tested
this in quite a long time.
