rtlwifi: Remove extra workqueue for enter/leave power state 



When the rtlwifi family of drivers was converted to use a workqueue when
entering or leaving power save mode (commits a269913c, a5ffbe0a,
41affd52, b9116b9a, and 6539306b), the code began scheduling work from
the callback routine of a different workqueue with a resulting increase in
overhead.
