mm/thp/autonuma: use TNF flag instead of vm fault

We are using the wrong flag value in task_numa_falt function.  This can
result in us doing wrong numa fault statistics update, because we update
num_pages_migrate and numa_fault_locality etc based on the flag argument
passed.

Fixes: bae473a423 ("mm: introduce fault_env")
