Filipe Manana 356056cbe6 btrfs: fix extent buffer leak after tree mod log failure at split_node() 
[ Upstream commit ede600e497b1461d06d22a7d17703d9096868bc3 ]

At split_node(), if we fail to log the tree mod log copy operation, we
return without unlocking the split extent buffer we just allocated and
without decrementing the reference we own on it. Fix this by unlocking
it and decrementing the ref count before returning.
