[PATCH AUTOSEL 4.19 041/123] aio: fix failure to put the file pointer

[Sasha Levin]

From: Jens Axboe <ax...@kernel.dk>

[ Upstream commit 53fffe29a9e664a999dd3787e4428da8c30533e0 ]

If the ioprio capability check fails, we return without putting
the file pointer.

Fixes: d9a08a9e616b ("fs: Add aio iopriority support")
