6.6-stable review patch. If anyone has any objections, please let me know.

From: Dave Jiang dave.jiang@intel.com
commit 54b9460b0a28c4c76a7b455ec1b3b61a13e97291 upstream.
For generic targets, there's no reason to call register_memory_node_under_compute_node() with the access levels that are only visible to HMAT handling code. Only update the attributes and rename hmat_register_generic_target_initiators() to hmat_update_generic_target().
The original call path ends up triggering register_memory_node_under_compute_node(). Although the access level would be "3" and not impact any current node arrays, it introduces unwanted data into the numa node access_coordinate array.
