IPoIB: Move ipoib_ib_dev_flush() to ipoib workqueue
Move ipoib_ib_dev_flush() to ipoib's workqueue. This keeps it ordered
with respect to other work scheduled by the ipoib driver. This fixes
problems with races, for example:
- ipoib_ib_dev_flush() has started running because of an IB event
- user does ifconfig ib0 down
- ipoib_mcast_stop_thread() gets called twice and waits for the same
completion twice
