vsock: use new wait API for vsock_stream_sendmsg()
As reported by Michal, vsock_stream_sendmsg() could still
sleep at vsock_stream_has_space() after prepare_to_wait():
vsock_stream_has_space
vmci_transport_stream_has_space
vmci_qpair_produce_free_space
qp_lock
qp_acquire_queue_mutex
mutex_lock
Just switch to the new wait API like we did for commit
d9dc8b0f8b4e ("net: fix sleeping for sk_wait_event()").
