[PATCH 9/9] monitor/hmp: Prefer to use hmp_handle_error for error report


From: Maxim Levitsky
Subject: [PATCH 9/9] monitor/hmp: Prefer to use hmp_handle_error for error reporting in block hmp commands
Date: Wed, 20 Nov 2019 20:58:50 +0200

This way they all will be prefixed with 'Error:' which some parsers
(e.g libvirt need)
