9p: Add missing read barrier in virtio zero-copy path
Commit 2b6e72ed747f ("9P: Add memory barriers to protect request
fields over cb/rpc threads handoff") added a read barrier after
p9_client_rpc() waits for req->status, pairing with the write barrier in
p9_client_cb(). The virtio zero-copy wait path was missed.
Add the same read barrier after the zero-copy wait before reading the
completed request.
Fixes: 2b6e72ed747f ("9P: Add memory barriers to protect request fields over cb/rpc threads handoff")
