hw/xen: convert stderr prints to error/warn reports

According to the QEMU Coding Style document:

> Do not use printf(), fprintf() or monitor_printf(). Instead, use
> error_report() or error_vreport() from error-report.h. This ensures the
> error is reported in the right place (current monitor or stderr), and in
> a uniform format.
> Use error_printf() & friends to print additional information.

This commit changes fprintfs that report warnings and errors to the
appropriate report functions.
