[PATCH v2] staging: rtl8712: usb_intf: Remove flush_scheduled_work()

[Bhaktipriya Shridhar <bhaktipriya96@gmail.com>]

flush_scheduled_work() flushes out all work items in system_wq.
Since one doesn't know what could be running there, flushing work items
individually is preferred.

Since there are finite number of work items to be flushed,(viz
pwrpriv->SetPSModeWorkItem,pwrpriv->SetPSModeWorkItem,pLed->BlinkWorkItem)
instead of flushing system_wq, each work item is separately flushed.
