Removed out of context sentence and improved a clarity of device creation parameters

One sentence seemed to be out of place, which I have replaced with another sentence that followed up on the code behind it. Lastly the information about parameters passed to the `vk::raii::Device()` were all in one sentence which was quite difficult to read.

 That means that the `enabledLayerCount` and `ppEnabledLayerNames` fields of
 `VkDeviceCreateInfo` are ignored by up-to-date implementations.
 
-As mentioned earlier, we need several device-specific extensions for our application to work properly.
+With the `vk::DeviceCreateInfo` filled in, we can now proceede with creating logical device.

+info we just specified. Additional and optional parameters are the allocation callbacks pointer and a pointer
 to a variable to store the logical device handle in. Similarly to the instance
 creation function, this call can throw errors based on enabling non-existent
 extensions or specifying the desired usage of unsupported features.
