[PATCH v2 7/9] jbd2: remove dead equality check of j_commit_[sequence/request] in kjournald2

[Kemeng Shi]

The j_commit_[sequence/request] are updated with j_state_lock held during
runtime. In kjournald2, two equality checks of j_commit_[sequence/request]
are under the same j_state_lock, then the second check is unnecessary.
