st/mesa: fix regression since a22aba4eae9b29db731487bce90e8292f7e82c72

"st/mesa: check image size before copy_image_data_to_texture()" caused
a regression in piglit fbo-generatemipmap-formats test on all gallium drivers.

Level 0 for NPOT textures will not match minified values, so don't do this
check for level 0.
