IB/qib: Handle transitions from ACTIVE_DEFERRED to ACTIVE better

Browse Source 
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.
