Looks good - but I can't help but think that it'd be nice to handle this
from io_wq_submit_work() instead, and take it out of the opcode
handlers themselves (like this one, and the recv/recvmsg part). That'd
put it in the slow path instead.

Anyway, it's applied, as it's a real fix and any work like the above
should be done separately of course.
