Subject: [PATCH net-next 4/5] vsock/test: use send_buf() in vsock_test.c
We have a very common pattern used in vsock_test that we can
now replace with the new send_buf().
This allows us to reuse the code we already had to check the
actual return value and wait for all the bytes to be sent with
an appropriate timeout.
