Btrfs: fix extent_buffer leak during tree log replay

During tree log replay, we read in the tree log roots,
process them and then free them.  A recent change
takes an extra reference on the root node of the tree
when the root is read in, and stores that reference
in root->commit_root.

This reference was not being freed, leaving us with
one buffer pinned in ram for each subvol with
a tree log root after a crash.
