anv/cmd_buffer: Adjust the image view reloc function

anv/cmd_buffer: Adjust the image view reloc function

Make the function take in an image instead of an image view. This
enables us to record relocations for surfaces states created outside of
the anv_CreateImageView path.

v2 (Jason Ekstrand):
- Use image->offset instead of surf_offset in aux_offset calculation.
