Btrfs: unlock extent and pages on error in cow_file_range
When I converted the BUG_ON() for the free_space_cache_inode in cow_file_range I made it so we just return an error instead of unlocking all of our various stuff. This is a mistake and causes us to hang when we run into this. This patch fixes this problem. Thanks, Signed-off-by: Josef Bacik <jbacik@fb.com>
