ovl: fix file reference leak when submitting aio

Commit 724768a39374 ("ovl: fix incorrect fdput() on aio completion")
took a refcount on real file before submitting aio, but forgot to
avoid clearing FDPUT_FPUT from real.flags stack variable.
This can result in a file reference leak.

Fixes: 724768a39374 ("ovl: fix incorrect fdput() on aio completion")
