md/raid10: check In_sync flag in 'enough()'. It isn't really enough to check that the rdev is present, we need to also be sure that the device is still In_sync. Doing this requires using rcu_dereference to access the rdev, and holding the rcu_read_lock() to ensure the rdev doesn't disappear while we look at it. Signed-off-by: NeilBrown <neilb@suse.de>
