seat: add check for NULL keyboard
Check for a NULL keyboard_state.keyboard value in seat_client_create_keyboard() before trying to use it, as is done in other functions like seat_client_send_repeat_info(). Prevents a segfault in certain situations on keyboard removal, as seen in the sway issue. Closes: https://github.com/swaywm/sway/issues/5205 Closes: https://github.com/swaywm/wlroots/issues/2073
