btrfs: move btrfs_truncate_block out of trans handle
Since we do a delalloc reserve in btrfs_truncate_block we can deadlock with freeze. If somebody else is trying to allocate metadata for this inode and it gets stuck in start_delalloc_inodes because of freeze we will deadlock. Be safe and move this outside of a trans handle. This also has a side-effect of making sure that we're not leaving stale data behind in the other_encoding or encryption case. Not an issue now since nobody uses it, but it would be a problem in the future. Signed-off-by:Josef Bacik <jbacik@fb.com> Signed-off-by:
