Jens Axboe 4716c73b18 io_uring: hold uring mutex around poll removal ...

Snipped from commit 9ca9fb24d5febccea354089c41f96a8ad0d853f8 upstream.

While reworking the poll hashing in the v6.0 kernel, we ended up
grabbing the ctx->uring_lock in poll update/removal. This also fixed
a bug with linked timeouts racing with timeout expiry and poll
removal.

Bring back just the locking fix for that.
