IB/qib: Fix over-scheduling of QSFP work
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. In combination with setting the physical IB link state
prior to the IBC being brought out of reset, this can cause the link
state machine to start training early with wrong settings.

IB/qib: Hold links until tuning data is available
Hold the link state machine until the tuning data is read from the
QSFP EEPROM so correct tuning settings are applied before the state
machine attempts to bring the link up. Link is also held on cable
unplug in case a different cable is used.

RDMA: Update workqueue usage
* ib_wq is added, which is used as the common workqueue for infiniband
instead of the system workqueue. All system workqueue usages
including flush_scheduled_work() callers are converted to use and
flush ib_wq.
* cancel_delayed_work() + flush_scheduled_work() converted to
cancel_delayed_work_sync().
* qib_wq is removed and ib_wq is used instead.
This is to prepare for deprecation of flush_scheduled_work().
