[PATCH v2 4/4] win32u: Send the total number of registered devices to the server.

[Rémi Bernon]

From: R��mi Bernon

Instead of device_count which is the number of registration updates,
and execute the request within the rawinput_mutex to ensure atomicity
of the update and consistency between the client and the server state.
