Implement invalidate MW and cleaned up invalidate MR operations.
Added code to perform remote invalidate for send with invalidate.
Added code to perform local invalidation.
Deleted some blank lines in rxe_loc.h.
Signed-off-by: Bob Pearson <rpearson@xxxxxxx>
---
v3:
Replaced enums in lower case with upper case and moved to
rxe_verbs.h which is where enums live.
