Mark ipoib device as initialized on device open.
Set the IPOIB_FLAG_INITIALIZED on dev_open and clear it on dev_stop to avoid a race between ipoib load and the underlying device driver. The device module must dispatch the IB_EVENT_PORT_ACTIVE event before ipoib module is loaded. Otherwise, the flush will fail since no one set the IPOIB_FLAG_INITIALIZED.
