Revert "ext4: wait on all pending commits in ext4_sync_fs()"
This undoes commit 14ce0cb411c88681ab8f3a4c9caa7f42e97a3184.
Since jbd2_journal_start_commit() is now fixed to return 1 when we
started a transaction commit, there's some transaction waiting to be
committed or there's a transaction already committing, we don't
need to call ext4_force_commit() in ext4_sync_fs(). Furthermore
ext4_force_commit() can unnecessarily create sync transaction which is
expensive so it's worthwhile to remove it when we can.
