io_uring/rw: forbid multishot async reads
At the moment we can't sanely handle queuing an async request from a
multishot context, so disable them. It shouldn't matter as pollable
files / socekts don't normally do async.
Patching it in __io_read() is not the cleanest way, but it's simpler
than other options, so let's fix it there and clean up on top.
