Subject: vsock: fix timeout in vsock_accept()
Git-commit: 7e0afbdfd13d1e708fe96e31c46c4897101a6a43
Patch-mainline: 5.7
References: networking-stable-20_06_07

The accept(2) is an "input" socket interface, so we should use
SO_RCVTIMEO instead of SO_SNDTIMEO to set the timeout.

So this patch replace sock_sndtimeo() with sock_rcvtimeo() to
use the right timeout in the vsock_accept().
