AF_VSOCK: Shrink the area influenced by prepare_to_wait
commit f7f9b5e7f8eccfd68ffa7b8d74b07c478bb9e7f0 upstream.
When a thread is prepared for waiting by calling prepare_to_wait, sleeping
is not allowed until either the wait has taken place or finish_wait has
been called. The existing code in af_vsock imposed unnecessary no-sleep
assumptions to a broad list of backend functions.
This patch shrinks the influence of prepare_to_wait to the area where it
is strictly needed, therefore relaxing the no-sleep restriction there.
