This new parameter can be "const".

The only change here is to indent, but it'd be slightly
more maintainable (proof against addition of new input types)
to test "if (input->type != QEMU_INPUT_TYPE_MOUSE)".
That way, if we ever add a third input type, this code would
remain in sync with the "mouse only" comment with no change required.
Same below.

"const" here, too.
