Don't over-schedule QSFP work on driver initialization. It could end up being run simultaneously on two different CPUs resulting in bad EEPROM reads. The above, in combination withe setting the physical IB link state prior to the IBC being brought out of reset can cause the link state machine to start training early with wrong settings.

This includes adding a new db_lock, a spin lock disabling BH too, used by the recovery thread and the ring_tx_db() paths to allow db drop recovery. - cleaned up initial db avoidance code. - add read_eq_indices() - allows the LLD to use the pcie mw to efficiently read hw eq contexts. - add cxgb4_sync_txq_pidx() - called by iw_cxgb4 to sync up the sw/hw pidx value. - add flush_eq_cache() and cxgb4_flush_eq_cache(). This allows iw_cxgb4 to flush the sge eq context cache before beginning db drop recovery. - add module parameter, dbfoifo_int_thresh, to allow tuning the db interrupt threshold value. - add dbfifo_int_thresh to cxgb4_lld_info so iw_cxgb4 knows the threshold. - add module parameter, dbfoifo_drain_delay, to allow tuning the amount of time delay between DB FULL and EMPTY upcalls to iw_cxgb4.

It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and vary the completion status as appropriate. The outer loop will call as many times as necessary.
