DirectInput: use correct joypad id 

Previously `joypad_count` was used as the index into the d_joypads array when initializing a new gamepad.
This caused the accidental override of an already connected device when a gamepad with a lower id was disconnected and connected again.

fixes #17566

(cherry picked from commit 802a0316c5)
