IPoIB/cm: Fix error handling in ipoib_cm_dev_open()
If skb allocation fails when we start the device, we call
ipoib_cm_dev_stop() even though ipoib_cm_dev_open() did not run to
completion, so we pass an invalid pointer to ib_destroy_cm_id and get
an oops.
Fix by clearing cm.id on error, and testing it in cm_dev_stop().
