Using an int value is causing qg->reserved to become negative and
exclusive -EDQUOT to be reached prematurely.

V1 had a reproducer, I think it's fine to keep it here so I'll copy it.

I am adding a testcase in (x)fstests which covers both qgroup issues for
which I have sent the patches. I am fine either ways.

The fstests testcase is orthogonal to the changelog describing the steps
to reproduce the bug (it could just roughly describe the idea), as it
helps to understand what's the patch going to fix.
