net/hns3: fix promiscuous mode for PF

Currently, when promiscuous mode is enabled, it is just allowed to
accept all the unicast and broadcast packets in hns3 PF PMD driver. It
should also be able to receive multicast packets.

Fixes: 19a3ca4c99cf ("net/hns3: add start/stop and configure operations")
