jbd: relocate assert after state lock in journal_commit_transaction()
The state lock is taken after we are doing an assert on the state
value, not before. So we might in fact be doing an assert on a
transient value. Ensure the state check is within the scope of
the state lock being taken.
Backport of jbd2 commit 3ca841c106fd6cd2c942985977a5d126434a8dd6
