REPLY_ACK features provide a generic way for QEMU to ensure both completion and success of a request. As described in vhost-user spec in QEMU repository, QEMU sets VHOST_USER_NEED_REPLY flag (bit 3) when expecting a reply_ack from the backend. Backend must reply with 0 for success or non-zero otherwise when flag is set. Currently, only VHOST_USER_SET_MEM_TABLE request implements reply_ack, in order to synchronize mapping updates. This patch enables REPLY_ACK feature generally, but only checks error code for VHOST_USER_SET_MEM_TABLE.
