Naohiro Aota bb166d7207 btrfs: fix NULL pointer dereference from free_reloc_roots() 
__del_reloc_root should be called before freeing up reloc_root->node.
If not, calling __del_reloc_root() dereference reloc_root->node, causing
the system BUG.

Fixes: 6bdf131fac ("Btrfs: don't leak reloc root nodes on error")
