net: hns3: fix incomplete uninitialization of IRQ in the hns3_nic_uninit_vector_data()
[ Upstream commit ae6017a71115ebc4e5c1a3f0f451319ab3f5c447 ]
In the hns3_nic_uninit_vector_data(), the procedure of uninitializing
the tqp_vector's IRQ has not set affinity_notify to NULL and changes
its init flag. This patch fixes it. And for simplificaton, local
variable tqp_vector is used instead of priv->tqp_vector[i].
