io_uring: fix uninitialized field in rw io_kiocb

[ Upstream commit 32452a3eb8b64e01e2be717f518c0be046975b9d ]

io_rw_init_file does not initialize kiocb->private, so when iocb_bio_iopoll
reads kiocb->private it can contain uninitialized data.

Fixes: 3e08773c3841 ("block: switch polling to be bio based")
