Otherwise, the index of an input device like a usb-kbd is silently accepted.
(qemu) info mice
Mouse #2: QEMU PS/2 Mouse
* Mouse #3: QEMU HID Mouse
(qemu) mouse_set 1
(qemu) info mice
Mouse #2: QEMU PS/2 Mouse
* Mouse #3: QEMU HID Mouse
Also replace monitor_printf() call in do_mouse_set() with error_report() and
adjust error message.
