Pavel Begunkov ca6b015316 io_uring: use WRITE_ONCE for user shared memory 
[ Upstream commit 93e197e524 ]

IORING_SETUP_NO_MMAP rings remain user accessible even before the ctx
setup is finalised, so use WRITE_ONCE consistently when initialising
rings.

Fixes: 03d89a2de2 ("io_uring: support for user allocated memory for rings/sqes")
