nv50,nvc0: detect underlying resource changes and update tic

nv50,nvc0: detect underlying resource changes and update tic

When updating texture buffers, we might end up replacing the whole
buffer. Check that the tic address matches the resource address, and if
not, update the tic and reupload it.

This fixes:
  arb_direct_state_access-texture-buffer
  arb_texture_buffer_object-data-sync
