[PATCH 5/7] btrfs: free pertrans at end of cleanup_transaction

[Boris Burkov <boris@bur.io>]

Some of the operations after the free might convert more pertrans
metadata. Do the freeing as late as possible to eliminate a source of
leaked pertrans metadata.

Helps with the pass rate of generic/269 and generic/475.
