[Qemu-devel] [PATCH v2 14/23] migration: Use error_reportf_err() instead of monitor_printf()

[Markus Armbruster <armbru@redhat.com>]

Using error_reportf_err() instead of monitor_printf() makes no
difference when monitor_printf() is used correctly, i.e. within an HMP
monitor.  Elsewhere, monitor_printf() does nothing, while
error_reportf_err() reports to stderr.

Both changed functions are HMP command handlers.  These should only
run within an HMP monitor.
