Commit 0ecdffbb created pc_boot_set() for use from monitor command "boot_set", via qemu_boot_set(). pc_boot_set() reports errors to cur_mon, which works fine for monitor code. Commit e0f084bf reused the function int reset handler restore_boot_devices(). Use of cur_mon is problematic in that context. For instance, the "Too many boot devices for PC" error for "-boot order=abcdefgh,once=c" goes to the monitor instead of stderr. The monitor may not even exist. Fix by switching to qemu_error().
