btrfs: fix extent map use-after-free when adding pages to compressed bio
At addrabiopages() we are accessing the extent map to calculate 'addsize' after we dropped our reference on the extent map, resulting in a use-after-free. Fix this by computing 'add_size' before dropping our extent map reference.
