[PATCH] smoke:fix the segment fault error

[juan.j.zhao at linux.intel.com]

From: Juan Zhao <juan.j.zhao at linux.intel.com>

Add widget_set_size in the initiate time to allow smoke get the
 correct surface later. Or it will report segment fault error
 because of the null surface.
Also add resize_handler to not allow resizing just like flower.
