IB/ehca: Remove reference to special QP in case of port activation failure
If the initialization of a special QP (e.g. AQP1) fails due to a software timeout, we have to remove the reference to that special QP struct from the port struct to stop the driver from accessing the QP, since it will be/has been destroyed by the caller, eg in this case ib_mad.
