[PATCH] IPoIB: Fix device removal race
Currently we may have work scheduled in default kernel workqueue when
the device is going down. The device could get freed before this
workqueue gets serviced. I am actually seeing this causing system
hangs.
The following patch fixes this by using ipoib_workqueue which gets
flushed when the device is going down.
