* keyboard - pointer to the keyboard, but unused

* LV_RES_OK if the *kb object was not deleted (freed),
* LV_RES_INV if it was deleted.

* Assumptions/Limitations:
* The animation routine will call kb_hide_anim_end() to delete (free)
* the object. The global lv_obj_t *kb is set to NULL after whether
* deleted or not. Assume *kb is valid entering this function.
