net: hns3: fix netif_napi_del() not do problem when unloading

When the driver is unloading, if a global reset occurs,
unmap_ring_from_vector() in the hns3_nic_uninit_vector_data() will
fail, and hns3_nic_uninit_vector_data() just return. There may be
some netif_napi_del() not be done.

Since hardware will unmap all ring while resetting, so
hns3_nic_uninit_vector_data() should ignore this error, and do the
rest uninitialization.
