net: hns3: fix incomplete uninitialization of IRQ in the hns3_nic_uninit_vector_data()

Browse Source 
[ Upstream commit ae6017a711 ]

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].

Fixes: 424eb834a9 ("net: hns3: Unified HNS3 {VF|PF} Ethernet Driver for hip08 SoC")
