lima: fix glCopyTexSubImage2D

The reload texture descriptor needs to take care of the mipmap level
and the layer in case of GL_TEXTURE_CUBE_MAP.

glCopyTexSubImage2D triggers the lima_blit function which ends in a draw.
A reload is necessary. The reload texture descriptor is always built with
just one mipmap level, but this needs to be the level we want to reload,
not just 0. We also have to take care of the cubemap face.

This fixes the following dEQP tests:

dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_rgb
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_rgba
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.cube_rgb
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.cube_rgba
