During __vsock_create() CAP_NET_ADMIN is used to determine if the vsock_sock->trusted should be set to true. This value is used later for determing if a remote connection should be allowed to connect to a restricted VM. Unfortunately, if the caller doesn't have CAP_NET_ADMIN, an audit message such as an selinux denial is generated even if the caller does not want a trusted socket. Logging errors on success is confusing. To avoid this, switch the capable(CAP_NET_ADMIN) check to the noaudit version.
