renderer: fix compressed transfer gets

Browse Source 
This code ended up in the other file and really wasn't necessary
there.

Remove the transfer code from virglrenderer.c, move into main
renderer file, and match it with the corresponding transfer
reader.

This should at least fix the crash in compressed textures
with ARB_get_texture_sub_image
