Lv_tabview_create() with copy does not initialize ext->tab_cnt

In [lvgl]/src/lv_objx/lv_tabview.c:lv_tabview_create(), in the /Copy an existing tab view/ leg, ext->tab_cnt is uninitialized (ought to be set to 0).

Failed spectatularly with LV_MEM_ADD_JUNK=1 in lv_mem.c.

Thanks for the report! I’ve just fixed it here.
