libcamera: request: Rename Private::reuse() to Private::reset()

The Request::Private::reuse() is different from Request::reuse().
It resets the members of Request::Private to default values hence,
rename it to a more appropriate Request::Private::reset().

Update the usage and documentation accordingly.
