migration: Use error_reportf_err() instead of monitor_printf()
Both error_reportf_err() and monitor_printf() print to the same
destination 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.
Unlike monitor_printf(), error_reportf_err() uses the error whole
instead of just its message obtained with error_get_pretty(). This
avoids suppressing its hint (see commit 50b7b00), but I don't think
the errors touched in this commit can come with hints.
