net: set FMODE_NOWAIT for sockets
The socket read/write functions deal with O_NONBLOCK and IOCB_NOWAIT just fine, so we can flag them as being FMODE_NOWAIT compliant. With this, we can remove socket special casing in io_uring when checking if a file type is sane for nonblocking IO, and it's also the defined way to flag file types as such in the kernel.
