cxgb4: Fix race condition in cleanup
There is a possible race condition when we unregister the PCI Driver and then
flush/destroy the global "workq". This could lead to situations where there
are tasks on the Work Queue with references to now deleted adapter data
structures. Instead, have per-adapter Work Queues which were instantiated and
torn down in init_one() and remove_one(), respectively.
v2: Remove unnecessary call to flush_workqueue() before destroy_workqueue()
