vhost: fix zero-copy server mode

Browse Source 
This patch fixes the situation where vhost-user cannot start as server
with dequeue_zero_copy enabled.

Using flag instead of vsocket->is_server to determine whether vhost-user
is in client mode. Because vsocket->is_server is not ready at this time.

Fixes: 715070ea10 ("vhost: prevent zero-copy with incompatible client mode")
