btrfs: fix NULL pointer dereference from free_reloc_roots()
commit bb166d7207432d3c7d10c45dc052f12ba3a2121d upstream.
__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: 6bdf131fac23 ("Btrfs: don't leak reloc root nodes on error")
