fs/aio-nr: fix decrement of aio-nr
Commit 280363c ("fs/aio: show real number of aio events in fs.aio-nr
sysctl")
changed only incrementing of fs.aio-nr counter. It failed to update
decrement path which leads to constant growing of fs.aio-nr value.
Fixes commit 280363c ("fs/aio: show real number of aio events in fs.aio-nr
sysctl").
