RDMA/hns: Fix incorrect clearing of interrupt status register

Browse Source 
[ Upstream commit ecb4db5c35 ]

The driver will clear all the interrupts in the same area
when the driver handles the interrupt of type AEQ overflow.
It should only set the interrupt status bit of type AEQ overflow.

Fixes: a5073d6054 ("RDMA/hns: Add eq support of hip08")
