extensions/khr/calibrated_device: Use self.handle instead of requir…

…ing `vk::Device` argument (#898)

When introducing this new `VK_KHR_calibrated_timestamps` extension based
on `VK_EXT_calibrated_timestamps` in #890 in parallel to finalizing
and merging the `Instance`/`Device` separation in #734, I seem to have
missed an opportunity to use the newly available `self.handle` for this
extension from `struct Device`, instead leaving an unnecessary
`device: vk::Device` argument in place.
