Jan Schmidt a95236d99f Btrfs: fix return value for __tree_mod_log_oldest_root
In __tree_mod_log_oldest_root() we must return the found operation even if
it's not a ROOT_REPLACE operation. Otherwise, the caller assumes that there
are no operations to be rewinded and returns immediately.

The code in the caller is modified to improve readability.
