parallels: dirty BAT properly for continuous allocations
This patch marks part of the BAT dirty properly. There is a possibility that multy-block allocation could have one block allocated on one BAT page and next block on the next page. The code without the patch could not save updated position to the file. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: Denis V.
