btrfs: use simple booleans for log_commit field in struct btrfs_root

We are using atomic types for the log_commit array of struct btrfs_root
but all we need is simple booleans. The log_commit array elements are
always protected by the root's log_mutex, both for writes and reads, so
we can use a simple boolean. The use of atomics if from the very early
days of the log tree code where the access to the fields was not protected
by any lock.

So switch to simple booleans, which results in cheaper code and slightly
reduces the object size too.
