net: hns3: enable broadcast promisc mode when initializing VF

[ Upstream commit 2d5066fc175ea77a733d84df9ef414b34f311641 ]

For revision 0x20, the broadcast promisc is enabled by firmware,
it's unnecessary to enable it when initializing VF.

For revision 0x21, it's necessary to enable broadcast promisc mode
when initializing or re-initializing VF, otherwise, it will be
unable to send and receive promisc packets.

Fixes: f01f5559cac8 ("net: hns3: don't allow vf to enable promisc mode")
