Dexuan Cui e0792a7682 vsock: fix possible infinite sleep in vsock_connectible_wait_data() 
[ Upstream commit 466a85336f ]

Currently vsock_connectible_has_data() may miss a wakeup operation
between vsock_connectible_has_data() == 0 and the prepare_to_wait().

Fix the race by adding the process to the wait queue before checking
vsock_connectible_has_data().

Fixes: b3f7fd5488 ("af_vsock: separate wait data loop")
