commit 7ceb17e87bde79d285a8b988cfed9eaeebe60b86 md: Allow devices to be re-added to a read-only array. allowed a bit more than just that. It also allows devices to be added to a read-write array and to end up skipping recovery. This patch removes the offending piece of code pending a rewrite for a subsequent release. More specifically: If the array has a bitmap, then the device will still need a bitmap based resync ('saved_raid_disk' is set under different conditions is a bitmap is present). If the array doesn't have a bitmap, then this is correct as long as nothing has been written to the array since the metadata was checked by ->validate_super. However there is no locking to ensure that there was no write. Bug was introduced in 3.10 and causes data corruption so patch is suitable for 3.10-stable.
