Xu Kuohai c1970e26bd selftests/bpf: Fix a CI failure caused by vsock write
While commit 90f0074cd9 ("selftests/bpf: fix a CI failure caused by vsock sockmap test")
fixes a receive failure of vsock sockmap test, there is still a write failure:

Error: #211/79 sockmap_listen/sockmap VSOCK test_vsock_redir
Error: #211/79 sockmap_listen/sockmap VSOCK test_vsock_redir
  ./test_progs:vsock_unix_redir_connectible:1501: egress: write: Transport endpoint is not connected
  vsock_unix_redir_connectible:FAIL:1501
  ./test_progs:vsock_unix_redir_connectible:1501: ingress: write: Transport endpoint is not connected
  vsock_unix_redir_connectible:FAIL:1501
  ./test_progs:vsock_unix_redir_connectible:1501: egress: write: Transport endpoint is not connected
  vsock_unix_redir_connectible:FAIL:1501

The reason is that the vsock connection in the test is set to ESTABLISHED state
by function virtio_transport_recv_pkt, which is executed in a workqueue thread,
so when the user space test thread runs before the workqueue thread, this
problem occurs.

To fix it, before writing the connection, wait for it to be connected.
