Pavel BegunkovandGreg Kroah-Hartman 1241052e15 io_uring: clean rings on NO_MMAP alloc fail ...

[ Upstream commit cef59d1ea7 ]

We make a few cancellation judgements based on ctx->rings, so let's
zero it afer deallocation for IORING_SETUP_NO_MMAP just like it's
done with the mmap case. Likely, it's not a real problem, but zeroing
is safer and better tested.
