Liav A 11ead5c84f Kernel: Get RefPtr<Device> from the DeviceManagement::get_device method ...

Instead of returning a raw pointer, which could be technically invalid
when using it in the caller function, we return a valid RefPtr of such
device.

This ensures that the code in DevPtsFS is now safe from a rare race
condition in which the SlavePTY device is gone but we still have a
pointer to it.
