Pavel Begunkov ef9f692d76 io_uring: dont remove file from msg_ring reqs 
commit ef0ec1ad03 upstream.

We should not be messing with req->file outside of core paths. Clearing
it makes msg_ring non reentrant, i.e. luckily io_msg_send_fd() fails the
request on failed io_double_lock_ctx() but clearly was originally
intended to do retries instead.
