io_uring/net: fix accept multishot handling
REQ_F_APOLL_MULTISHOT doesn't guarantee it's executed from the multishot
context, so a multishot accept may get executed inline, fail
io_req_post_cqe(), and ask the core code to kill the request with
-ECANCELED by returning IOU_STOP_MULTISHOT even when a socket has been
accepted and installed.
