IB/hns: Optimize code of aeq and ceq interrupt handle and fix the bug of qpn

This patch optimized the codes of aeq and ceq interrupt handle
and fixed the bug in the calculation of qpn. For the special
qp(GSI or SMI), calculated the qp number according to physical
port and the qpn reported in the event of async event queue.
