[PATCH] btrfs: use list_for_each_entry_safe() when delete items

From: Azat Khuzhin
Date: Sat Jul 27 2013 - 06:13:11 EST

Replace list_for_each_entry() by list_for_each_entry_safe() in

There is another place that delete items lock_stripe_add(), but there we
don't need safe version, because after deleting we exit from loop.
