io_uring: refactor sendmsg/recvmsg iov managing
Current iov handling with recvmsg/sendmsg may be confusing. First make a
rule for msg->iov: either it points to an allocated iov that have to be
kfree()'d later, or it's NULL and we use fast_iov. That's much better
than current 3-state (also can point to fast_iov). And rename it into
free_iov for uniformity with read/write.
Also, instead of after struct io_async_msghdr copy fixing up of
msg.msg_iter.iov has been happening in io_recvmsg()/io_sendmsg(). Move
it into io_setup_async_msg(), that's the right place.
