We keep track of the first unscrubbed page in a page buddy using first_dirty
field. For now it can have two values, 0 (whole buddy needs scrubbing) or
INVALID_DIRTY_IDX (the buddy does not need to be scrubbed). Subsequent patches
will allow scrubbing to be interrupted, resulting in first_dirty taking any
value.
