btrfs: always drop log root tree reference in btrfs_replay_log()

[ Upstream commit 2f5b8095ea47b142c56c09755a8b1e14145a2d30 ]

Currently we have this odd behaviour:

1) At btrfs_replay_log() we drop the reference of the log root tree if
   the call to btrfs_recover_log_trees() failed;

2) But if the call to btrfs_recover_log_trees() did not fail, we don't
   drop the reference in btrfs_replay_log() - we expect that
   btrfs_recover_log_trees() does it in case it returns success.

Let's simplify this and make btrfs_replay_log() always drop the reference
on the log root tree, not only this simplifies code as it's what makes
sense since it's btrfs_replay_log() who grabbed the reference in the first
place.
