net/ixgbe: fix VF Rx mode for allmulticast disabled

Some customers find that 82599 NIC DPDK VF PMD can't receive any
broadcast packets when it is bound to igb_uio in the first time
to run a DPDK application like testpmd. But when the application
is quited and run again, the DPDK VF PMD can receive broadcast
packets again. The associated PF is run by kernel driver when
the VF is driven by DPDK PMD.

Fixes: 72dec9e37a84 ("ixgbe: support multicast promiscuous mode on VF")
