mm: make rmap_one boolean function
rmap_one's return value controls whether rmap_work should contine to
scan other ptes or not so it's target for changing to boolean. Return
true if the scan should be continued. Otherwise, return false to stop
the scanning.
This patch makes rmap_one's return value to boolean.
