drm/i915: Switch eviction code to use vmas
The execbuf wants to do relocations usings vmas, so we need a
vma->exec_list. The eviction code also uses the old obj execbuf list
for it's own book-keeping, but would really prefer to deal in vmas
only. So switch it over to the new list.
Again this is just a prep patch for the big execbuf vma conversion.
