IB/qib: Handle transitions from ACTIVE_DEFERRED to ACTIVE better
When the link transitions from ACTIVE_DEFERRED to ACTIVE, the driver only sees the ACTIVE state. With this change, it will check whether the state was already ACTIVE and if so, it will not generated IB events and will not clear symbol error counts.
