[PATCH] ksm: Stop iterating VMAs when ksm_test_exit returns true

[Wang Wensheng]

In scan_get_next_rmap_item() the break statement only exits the inner
while loop, leaving remaining VMAs to be iterated even if ksm_test_exit()
returns true. Replace it with a goto statement to avoid the unnecessary
work.
