drm/amdkfd: Output migrate end event if migrate failed

Browse Source 
If page migration failed, also output migrate end event to match with
migrate start event, with failure error_code added to the end of the
migrate message macro. This will not break uAPI because application uses
old message macro sscanf drop and ignore the error_code.

Output GPU page fault restore end event if migration failed.
