Markus Armbruster ac7ff4cf5f qsp: Simplify how qsp_report() prints
qsp_report() takes an fprintf()-like callback and a FILE * to pass to
it.

Its only caller hmp_sync_profile() passes monitor_fprintf() and the
current monitor cast to FILE *.  monitor_fprintf() casts it right
back, and is otherwise identical to monitor_printf().  The
type-punning is ugly.

Drop the callback, and call qemu_printf() instead.
