net: xilinx: axienet: Always disable promiscuous mode
[ Upstream commit 4ae738dfef2c0323752ab81786e2d298c9939321 ]
If promiscuous mode is disabled when there are fewer than four multicast
addresses, then it will not be reflected in the hardware. Fix this by
always clearing the promiscuous mode flag even when we program multicast
addresses.
