Jens Axboe 1d9dc9bed9 io_uring/net: disable partial retries for recvmsg with cmsg
commit 78d0d2063bab954d19a1696feae4c7706a626d48 upstream.

We cannot sanely handle partial retries for recvmsg if we have cmsg
attached. If we don't, then we'd just be overwriting the initial cmsg
header on retries. Alternatively we could increment and handle this
appropriately, but it doesn't seem worth the complication.

Move the MSG_WAITALL check into the non-multishot case while at it,
since MSG_WAITALL is explicitly disabled for multishot anyway.
