ixgbe: fix bcast packets Rx on VF after promisc removal
commit 803e9895ea2b0fe80bc85980ae2d7a7e44037914 upstream.
After a VF requested to remove the promiscuous flag on an interface, the
broadcast packets are not received anymore. This breaks some protocols
like ARP.
In ixgbe_update_vf_xcast_mode(), we should keep the IXGBE_VMOLR_BAM
bit (Broadcast Accept) on promiscuous removal.
This flag is already set by default in ixgbe_set_vmolr() on VF reset.
Fixes: 8443c1a4b192 ("ixgbe, ixgbevf: Add new mbox API xcast mode")
